Description
Bolster Armouries was founded with one primary mission: To provide Airsofters with a range of RIFs which has been fine-tuned to provide the absolute peak in attainable performance together with breathtaking external quality. Each of our replicas is hand-assembled by some of the most experienced Airsoft gun-techs in the industry and is built to an exacting standard.
Conceived with the modern Airsofter in mind, Bolster Armouries RIFs sport some of the finest internal and external upgrades available on the Airsoft market today, and are guaranteed to provide unparalleled performance. To underline their dedication to their products, every Bolster Armouries RIF is issued with a dedicated extended warranty and service package, ensuring you get the complete experience the creators intended.
The ONYX SBR is Bolster Armouries' answer for those asking for a short, lightweight M4/AR15 platform with absolutely superb handling sporting the most modern ergonomic enhancements on the market today. The ONYX is in every way an advanced AEG, having been fully upgraded internally with all the most reputable names in the industry, and parts veteran Airsoft gun-techs, skirmishers and competition shooters have held in high esteem for many years.
The combination of rock solid externals with stylish aesthetic alterations made, and a finely tuned gearbox driven by the incredible Warhead Industries motor and kept in check by the highly advanced TITAN MOSFET from GATE are what elevates the ONYX SBR above any other "off the shelf" AEG.
As the second revision of the ONYX AEG platform, the Forged Edition adds some choice internal reinforcements to the already bomb-proof ONYX SBR, with the goal of trying to further extend the lifespan of this high performance platform. All previously built ONYX AEGs that have been back for servicing have also been internally upgraded to the Forged Edition standard through the Bolster Armouries service plan. A Guarder Reinforced Tappet Plate has been added to provide a greater number of cycles before wear develops, and a Prometheus EG Hard Bevel Gear has been installed to more effectively deliver power from the Warhead motor with greater efficiency and reduced friction.
A new PTS QD suppressor has also been added, and the original right-side magazine release has been replaced with a CNC machined Maxx Model ambidextrous replacement with the same gorgeous metallic blue finish as the Maxx Model speed trigger, offering improved ergonomics over the original and gelling perfectly with the Bolster Armouries custom aesthetic.
If the mass-produced guns from other manufacturers are the equivalent of a Ford, a Bolster Armouries AEG is a Rolls Royce; crafted with care, to perfection, with the highest quality parts available and a distinctive external look leaving onlookers in no doubt that this is a Bolster Armouries AEG.
Bolster Armouries ONYX SBR
The base platform for the Bolster Armouries ONYX platform is the Krytac Barrett REC 7, widely regarded as having some of the highest quality core external parts available. The only parts retained from the original REC7 are the outer barrel, receiver, buffer tube, and handguard; everything else has been stripped to make room for the Bolster Armouries' internal and external magic.
The REC7 parts in the ONYX build are constructed from Aluminium and finished with a CNC machining process. The handguard features a monolithic style 20mm Picatinny rail which meets the receiver rail seamlessly, providing an uninterrupted attachment surface suited for practically any optical sight setup, including combinations of Holographic sights with magnifiers or night vision monoculars.
The REC 7 handguard uses the M-LOK negative space attachment interface to keep the weight of the ONYX down to only what is necessary, whilst offering the option to add any M-LOK compatible accessory, including M-LOK to Picatinny rail adapters. The 9.5-inch handguard has an octagonal profile, and provides M-LOK at the 3, 6, and 9 o'clock position, with Picatinny rail at the 12 o'clock position.
The smooth edges of this handguard make it a pleasure to hold, unlike many other metallic handguards which require rail covers for comfort. The REC7 handguard was chosen by the Bolster Arms team for this reason. Having a handguard which requires no additional rail covers or grips to provide a comfortable hold means you can keep the ONYX in its bare bones configuration if you prefer a simple setup, or deck it out to the nines if the mission requires it.
The REC7 receiver retains the beautiful, authentic, and fully licensed Barrett Firearms trademarks on the left side of the magazine well, reading; BARRETT|FIREARMS MFG INC|MURFREESBORO, TN|REC7|CAL. MULTI. These markings are precisely engraved and add a touch of realism to the ONYX, with a nod to one of the most well known firearms manufacturers out there.
The ONYX is a perfect replica of the real Barrett REC7, down to every protrusion, surface angle and finish, as one would expect when using a Barrett licensed AEG Shell. The receiver matches the form of a standard AR15 receiver, with its mock ejection port positioned on the right side of the upper receiver, followed by a mock brass defector and mock forward assist. The right side of the upper receiver features a standard-shaped AR15 cam pin protrusion, matching with that of the real Barrett REC 7.
The lower receiver is where you will find the controls of the ONYX, with the fire selector being located just above the pistol grip in a very accessible location which is one of the traits the AR15 platform is known and loved for. The selector switch provides 3 positions; Safe, Semi-automatic, and fully automatic with a 90-degree throw between each mode. Each selector position is denoted with an engraved pictogram, following trends in modern firearms development and imitating real Barrett REC7 perfectly.
The Forged Edition of the ONYX adds ambidextrous functionality in the form of the Maxx Model Advanced Magazine Release which replaces the stock Krytac part with a CNC machined aluminium replacement finished in alluring metallic blue to match the ONYX aesthetic.
Each of the extended mag release buttons lie well within reach of the trigger finger for either a left or right-handed user and is ideally suited to modern shooting techniques which often require weapons manipulation to be performed from both the strong and weak shoulder to take advantage of cover and gain an advantageous shooting position. This magazine release is a "drop-free" design, granting additional speed when time is of the essence; whether you are skirmishing or shooting against the clock.
CERAKOTE Finish - Northern Lights
Cerakote is an advanced, hard-wearing, and corrosion resistant ceramic coating developed for industries ranging from automotive to firearms and aerospace applications. Cerakote is offered in a wide range of finishes and is generally considered to be superior to anodizing when it comes to providing a custom finish to firearms. This is due in part to the high standards of colour consistency with a Cerakote finish, and that as a part of the process, anodizing creates a brittle and porous oxide layer over the parts, increasing tensile residual stress which can cause the finish to crack.
Cerakote does not affect the fatigue properties of aluminium and its alloys, making it ideal for Bolster Armouries RIFs. Cerakote has been extensively tested and has shown to be capable of exceeding military standards for corrosion resistance by over 40 times when subjected to a salt chamber test, even outlasting the commonly used Nitride finish for the barrels of real rifles.
The Cerakote "Northern Lights" finish is a stunning colour-changing navy blue which transforms into a greenish teal with glistening gold metallics when tilted, providing an extremely eye-catching finish and an absolutely distinctive overall look. This coating has been applied to the outer barrel and buffer tube of the ONYX SBR, providing a subtle contrast with the Tungsten finish and highlighting the ONYX SBR's nature as a truly custom Airsoft gun.
Northern lights is a part of the Cerakote H series of coatings, which boast excellent wear resistance, chemical and solvent resistance, and superb adhesion. The Northern Lights finish is visible through the ports on the handguard, and through the draining holes on the Magpul CTR stock, leaving observers in no doubt that this is a Bolster Armouries custom piece.
PTS Syndicate Ergonomic Enhancements
The Bolster Armouries ONYX has been equipped with a host of PTS Syndicate ergonomic enhancements to ensure it handles as well as it shoots.
The pistol grip has been replaced with the advanced EPG Pistol grip, offering a highly supportive design with a curved extension to help you maintain a comfortable hold and protect the web of your hand whilst manipulating the ONYX platform. This Pistol grip is constructed from Dupont Zytel, a high strength, abrasion and impact resistant thermoplastic polyamide/nylon. With comfortable dot texturing on either side, and crackle texture on the front strap and backstrap, this grip is the perfect enhancement to ensure an ONYX wielding player maintains a positive grip on the rifle in any weather condition, even whilst wearing thick gloves. The EPG follows a very similar profile to the popular Magpul MIAD and MOE grips for real AR15s, both of which have an excellent reputation for providing a comfortable grip which suits a wide variety of hand shapes and sizes.
This pistol grip is paired with a PTS Syndicate Fortis Shift Grip, a very recent design intending to provide the functionality of both a vertical foregrip and an angled foregrip. The Fortis Shift Grip is machined from a single piece of billet 6061-T6 aluminium and is a skeletonised design weighing in at a minuscule 104g whilst availing itself of all the structural advantages of aluminium construction. This grip can be used with either with a traditional vertical grip hold, the more modern thumb-break or thumb overbore (also known as "C clamp") grip, or even as a hand stop whilst retaining the flexibility to switch between grip methods when shooting from unconventional positions in a dynamic skirmishing environment.
The ONYX platform has been equipped with a PTS Radian Raptor-LT charging handle, the latest iteration of the revolutionary Radian Weapons ambidextrous charging handle, now adapted for Airsoft use by PTS Syndicate. This charging handle allows easy access for both left and right-handed users due to its dual-wing design and functions identically from either side of the rifle. The charging handle is comprised of a 6000 series aluminium skeleton with a black anodized finish which is over-moulded with PTS' own custom reinforced polymer formula; known for its combination of high strength, low weight, and impressive durability.
The design of the Raptor charging handle allows the handle to be pulled with a single finger, thumb, or even the palm of your hand due to its serrated grip surfaces on the charging handle "wings" providing positive grip in any situation. The right side "wing" of the Raptor is slightly longer than the left side in order to clear the mock forward assist button found on the ONYX, allowing smooth operation with no snags for a left-handed user, or a right-hander who uses shoulder to shoulder transitions to gain the edge in close quarters. Pulling the charging handle to the rear provides access to the Pro-Win CNC aluminium rotary HOP, which is accessible through the mock ejection port on the right side of the ONYX.
PTS MK18 SD Quick Detachable Suppressor w/ PTS51T Flash Hider
To pair with the updated ONYX AEG the Bolster Armouries team has selected the PTS MK18SD suppressor for its aggressive looks and advanced QD design. This suppressor is modelled after a widely used real steel design which is issued to US Navy SEALs for use with their MK18 and HK416 rifles, as its name suggests. The PTS MK18SD is constructed from aluminium with an anodised matt black finish and mounts to the ONYX via the PTS 51T tri-prong flash hider and its unique locking ratchet system.
The 51T flash hider is the same device found on modern SCAR rifles and is a tri-prong design with weight-reducing fluting on each of the three prongs to avoid adding excess weight to the front end and inhibiting manoeuvrability. The flash hider is constructed from steel alloy, guaranteeing precise engagement with the locking mechanism inside the suppressor, and allowing it to be added and removed frequently without any wear developing.
The suppressor locks to the flash hider via a large thread with a fine-toothed ratchet surrounding the collar of the device to secure it in place. To remove the suppressor all that is needed is to hold the release button down and unscrew the suppressor. The suppressor only requires a single complete turn to remove, making it one of the fastest and simplest QD mechanisms on the suppressor market with the added benefit of consistently locking in the same orientation every single time it is mounted.
The MK18SD suppressor also boasts linear fluting surrounding the rear section which is present to help disperse heat at this critical point in the real steel suppressor design. The fluting only adds to the menacing appearance of the suppressor, and pairs perfectly with its wide 40mm diameter ridged tube to set it apart from prolific and commonplace smooth-sided cylindrical Airsoft suppressors.
Despite its larger overall form than the previous PTS Griffin M4SD supplied with the original ONYX, the PTS MK18SD weights a minuscule 284g, adding very little weight to the front end of the ONYX to keep its in-game agility and superlative handling qualities. The overall length of the MK18SD suppressor is approximately 6.7 inches, adding a manageable amount of additional length whilst maintaining the elegant balance and feel the original ONYX was renowned for.
Genuine Magpul CTR Stock
The Magpul CTR stock is widely regarded as the best AR15 carbine stock available for the vast majority of applications and is designed to be used with AR15 rifles with a mil-spec buffer tube. This stock has been seen in use with US Army Special Forces, US Navy SEALS, and our own UKSF, the special force's directorate comprising the SAS, SBS, SRR, and SFSG (1 PARA).
The CTR is an "A-frame" design, intended to keep the weight of the stock to a minimum whilst retaining optimal strength. The adjustment latch of the CTR is concealed within the A-frame design, avoiding snagging on slings or other equipment, and keeping the latch shielded from inadvertent activation. A premium chrome-silicone lock spring is used in the adjustment mechanism to provide dependable locking and long life.
The top of the stock has a sloping profile to provide a comfortable cheek weld whilst retaining a slim footprint. The sling mounting options provided on the CTR stock include; a QD sling socket on either side (accommodates up to 1.5" swivels), 1.25" sling loops on the bottom of the A-frame and at the rear, and a lanyard hole at the toe of the stock which is perfect for custom paracord sling solutions.
The CTR also features a "friction lock" system, intended to eliminate any wobble between the stock and buffer tube for enhanced weapon stability and a premium feel. The adjustment latch includes moulded in linear texturing to ensure that when you need to make an adjustment, there is no chance of slipping off the latch. The friction lock can be found on the bottom of the stock, at the front, and will pop open when the adjustment latch is pressed. After selecting your adjustment, simply squeeze the friction lock closed to eradicate any movement in the stock.
To ensure the stock stays firmly in your shoulder the CTR includes a removable 0.3" rubber butt pad with an anti-slip surface which also serves to increase impact protection in case the rifle is dropped on the stock. This stock has been copied by a plethora of Chinese factories, but the copies are known for their, to put it mildly, "approximate" tolerances, and have been the cause of many facial injuries when used on real rifles. The use of a genuine Magpul CTR on the ONYX affords it the best stock money can buy, with the advanced design and inherent strength of Magpul's advanced high density polymer.
Internal Enhancements
The internal parts present in the Bolster Armouries ONYX are hand selected for the high quality materials used in their construction, as well as for their exceptional performance. Each Bolster Armouries Gearbox is hand built, with each gear being perfectly shimmed for smooth operation, and the piston position also being corrected for the perfect Angle of engagement (AOE) to provide maximum efficiency and longevity.
This gearbox is matched with one of the most well-regarded steel tight bore inner barrels out there, renowned for its rigidity and high quality internal finish, coupled with the precision machined Pro-Win rotary HOP-up unit and a Prometheus purple HOP rubber which is based on the original Marui design but is comprised of longer lasting materials. Let's have a closer look at what goes into an ONYX AEG, and why these parts are so noteworthy:
Prometheus 6.03mm EG Inner Barrel - Stainless Steel
Improves accuracy - Enhanced Air seal - Click for more info
The Prometheus 6.03mm EG inner barrel is constructed from SUS 304 stainless steel (also known as SS304 or AISI304), with a chromium content of between 18% and 20% and nickel content between 8% and 10.5%. This choice of material not only gives the inner barrel exceptional rigidity, but has higher corrosion resistance than other stainless steels, aluminium, or brass used in other inner barrels.
This inner barrel was chosen primarily for its reputation as one of the best AEG upgrades money can buy, but also its precise dimensional tolerances which are guaranteed to be within 1/100th of a millimetre of the manufacturer's specs. This means we can confidently say your Bolster Arms AEG will shoot straight and true, as long as you do your part! This part also serves as a great way to increase the FPS of an AEG by a small amount without adding additional strain to the gearbox, simply by using the compressed air provided by the piston more efficiently.
Prometheus Purple HOP-up Rubber - Soft Rubber
Wear resistant - Improved HOP-up effect - Click for more info
Known amongst Airsofters as a "Prommy purple", the Prometheus Purple HOP-up Rubber is based on the original and proven Tokyo Marui HOP-up rubber design but is cast in a far more wear resistant rubber whilst maintaining the prerequisite softness necessary for a strong HOP effect.
This HOP-up rubber has become a household name in Airsoft, next to the Guarder Clear, but the Prommy purple has, in recent years become the HOP-up bucking of choice for those attempting a Flat HOP modification. This mod intends to increase the effect of the HOP-up by widening the area of contact with the BB and is generally home-brewed and can have wildly varying results, often requiring extensive testing and troubleshooting. This brings us seamlessly on to our next part...
Maple Leaf Delayer OMEGA Nub - Hard Rubber
Wide contact surface - Stronger HOP-up effect - Click for more info
The Maple Leaf OMEGA HOP-up nub is intended to be a mass-produced alternative to the home-brewed R-HOP and flat HOP modifications of yesteryear. This provides the kind of performance you would expect from a very well made flat HOP modification, but with no chance of potential jams and considerably less likelihood of failure due to its single piece design.
The OMEGA nub has a concave contact surface, shaped to match that of a 6mm BB perfectly, providing HOP effect across the entire upper surface of the BB, instead of just a single point in the centre. This provides excellent side-to-side stability and an increased HOP effect, extending the range of the AEG into the borderline implausible!
Pro-Win HOP-up Unit - CNC Machined Aluminium
Fine adjustments possible - Enhanced air seal - Click for more info
Pro-Win HOP-up units are another of those staple high grade internal components which have been serving Airsofters well for decades in their various forms. The unit inside the Bolster Armouries ONYX is a rotary design, providing a wider range of adjustment and improved ability to hold its setting under the vibration of firing when compared to the legacy gear HOP-up design. The Pro-Win HOP-up unit is constructed from CNC machined Aircraft grade aluminium and is finished in an attractive metallic blue anodizing.
You can pull back your charging handle to "pop the hood", and show off your Pro-Win HOP unit, and this awesome finish will definitely raise an eyebrow or two, marking your gun out as a custom piece. This precisely machined unit provides unparalleled air seal, adding to the already vastly improved efficiency of the ONYX platform. When coupled with the Prometheus Purple HOP bucking, this unit improves FPS without adding more strain to the gearbox; a fundamental goal throughout the Bolster Armouries AEG project.
Lonex Air Seal Loading Nozzle - POM Polymer
Low friction design - Internal O-ring for improved efficiency - Click for more info
The Lonex Air Seal nozzle is a marked improvement on the original Marui air nozzle design, featuring an internal O-ring to guarantee excellent air seal and consistent performance. The Lonex nozzle is made from POM material (Polyoxymethylene - also known as Acetal, Polyacetal, or Polyformaldehyde) which is a well known thermoplastic used in engineering applications requiring precise form with perfect dimensional stability, low friction, and high mechanical stiffness.
This nozzle is well regarded amongst Airsoft techs, including our Bolster Armouries tech team, and has found its way into the ONYX build after providing excellent performance whilst being practically bomb proof in their personal builds. Each nozzle installed in the ONYX platform has been measured with callipers and confirmed to be in spec (21.23mm long) prior to installation.
Lonex Cylinder head - CNC Machined Aluminium
Double O-ring configuration - Improved efficiency - Click for more info
As with Lonex's nozzle, the Lonex Cylinder head has taken the original Marui design and refined it with improved materials, polished surfaces, and a reprofiled inner nozzle, allowing the loading nozzle to move back and forth with as little resistance as possible. The Lonex Cylinder head is CNC machined from a single piece of aircraft-grade aluminium, granting it the strength it needs to contend with the other high end parts in the ONYX gearbox.
One of the most noteworthy enhancements in the Lonex Cylinder head is its double O-ring configuration, which is designed to provide excellent air seal, even when installed in a less than high quality Airsoft gearbox. This emphasis on efficiency and tight air seal means this goes even further inside a properly built gearbox like the one in the ONYX, and it falls perfectly in line with one of the Bolster Armouries goals; to maximize the efficiency of the Airsoft gearbox.
Airlab Sorbothane Pad (70D Hardness) - 70 Degree Sorbothane with polyurethane pad
Corrects Angle of engagement - Reduces stress on the gearbox - Click for more info
A Sorbothane pad (also known as a "sorbo pad") serves the role of protecting the front of the gearbox from the impact of the piston head during cycling. This prevents cracks from developing in demanding, high strain gearbox setups by absorbing the intense shock from the piston head impacting the cylinder head under spring tension. The material used, Sorbothane, is a visco-elastic polyurethane which provides superb shock absorption and sound dampening qualities whilst retaining its shape due to its elasticity. A 70-degree sorbo pad was chosen by the Bolster Armouries team to provide the best compromise between shock absorption and shape retention.
The sorbo pad also provides a secondary function; to correct the angle of engagement (AoE) of the sector gear in relation to the piston. This improves the lifespan of the piston by ensuring the piston and sector gear mesh properly and that undue strain is not applied to the very tips of the piston teeth. Also installed with the Airlab sorbo pad is Airlab's polyurethane pad, which was devised by them as a way of increasing the durability of the sorbo pad and preventing it from degrading after repeated piston head impacts. The Airlab Sorbo pad is manufactured in the UK.
Maxx Model CNC Hardened Stainless Steel Cylinder - CNC Machined Steel
Extremely tight tolerances - Polished inner surface - Click for more info
The Maxx model cylinder is machined from high strength stainless steel using CNC machining processes. To ensure consistent air compression and reduce friction, and thus wear on the piston, the Maxx Model cylinder is precisely machined to tight tolerances, with a high polish applied to its internal surfaces.
Having a high quality cylinder installed is another way the Bolster Armouries gearbox maximizes efficiency, squeezing every last bit of usable air from each piston cycle, giving you higher FPS without adding strain to the gearbox. The cylinder chosen for the ONYX AEG is the Type A variant, which is optimized for barrel lengths between 450 and 550mm.
Maxx Model CNC Aluminum Double O-Ring Bearing Piston Head - CNC Machined Aluminium Alloy
Enhanced compression - Improved shot to shot consistency - Click for more info
The Maxx Model piston head is CNC machined from a single piece of aluminium alloy in order to combine strength with low weight, which are both essential characteristics for a piston head used in a high performance gearbox. This piston head is also a ported design, intended to enhance compression and work together with the other enhanced gearbox internals to get the absolute best efficiency possible out of the ONYX platform.
The double O-ring configuration of this piston head helps prevent any air leaks between the piston head and cylinder, and the ball bearings within the piston head help reduce the strain on the part as it cycles under spring tension. A high quality piston head is one of the key parts installed to minimize fluctuations in FPS between shots. Wide variation in FPS is, without a doubt, the main factor in causing a lack of accuracy in Airsoft AEGs. With the Maxx Model piston installed, your ONYX AEG will have minimal variation in velocity, shot to shot. This makes for a consistently performing replica that you can reliably use to get first shot hits, with accuracy second to none.
Maxx Model CNC Aluminium Advanced Speed trigger - CNC Machined Aluminium and Titanium
Adjustable trigger travel - Ultra-responsive trigger - Click for more info
The Maxx model advanced speed trigger is specifically designed to facilitate a fast trigger response, a smooth and consistent trigger pull, and can be adjusted at multiple points to control the trigger pre-travel and reduce over-travel. This trigger is designed to work well with the GATE TITAN MOSFET to provide practically instantaneous trigger response and an ultra-fast fire rate on semi-automatic.
The trigger is machined from a single piece of aircraft-grade aluminium using CNC processes, with a separate titanium pivot pin for maximum durability. The trigger shape is intended to provide a natural trigger position for the vast majority of hand sizes and has chamfered edges and three rubber pads to ensure comfort, enhance traction and provide positive control of the trigger.
SHS Purple 15-Tooth Piston - Reinforced Polymer with Carbon Steel teeth
Low weight improves cyclic rate - High strength teeth - Click for more info
The SHS purple piston is comprised of two parts, combined to provide the best compromise between keeping the weight low, and the rigidity high. The piston body is constructed from fibre reinforced polymer, providing ample strength to resist the strain from rapid cycling whilst keeping the weight to a minimum.
The piston teeth which mesh with the steel sector gear are constructed from high carbon steel to provide the rigidity required for long term use alongside steel gears revolving at an incredible rate under spring tension. Despite its full steel tooth rack, the SHS piston weighs a mere 34g, keeping it well within the design parameters of the upgraded ONYX gearbox.
ASG Ultimate Milspec M115 Spring - Ferrosilicochrome with Zinc coating
Reduces strain on the gearbox internals - Corrosion Resistant - Click for more info
The ASG M115 spring is constructed from SiCr Alloy (also known as Ferrosilicochrome), with a zinc coating to discourage corrosion. This Alloy is well known for its use in manufacturing springs for the automotive industry and many others requiring static torsion loaded springs with high corrosion resistance.
The spring is a non-linear design, reducing strain on the gearbox by varying the coil tension over the course of compressing the spring. This means the spring design takes advantage of the points in the cycle of the AEG where the piston is in the best position to handle the high strain, such as the midpoint, whilst reducing the initial load on the piston teeth.
The Ultimate Milspec spring has closed and flattened ends which reduce wear on the piston, and minimize the chance of it failing. This particular spring was chosen due to its ability to reduce the strain on the internal components in the high speed ONYX gearbox whilst providing the necessary velocity, and its design which provides optimal performance with a 6.03mm tight bore inner barrel.
Prometheus Krytac Spur Gear Spacer - CNC Machined Aluminium
Ensures a perfect shim job - Reduced internal wear - Click for more info
The original Krytac steel gearset is equipped with self-shimming spring spacers on its spur gear, which reduces the need for complex and long winded shimming by attempting a "one size fits all" solution. This can be great for amateurs who want to upgrade their gearbox, as it removes the need to carry out the shimming process, which is one of the more difficult aspects of building a smooth running gearbox.
There are no amateurs at Bolster Armouries, and the main issue the Bolster team identified with this system is that whilst preferable to a bad shim job, the self-shimming spring spacers can cause additional rotational stress resulting in an increase in gear and motor noise, and long term wear.
The spring spacer originally inside the Bolster Armouries ONYX has been removed from the spur gear, replaced with the Prometheus CNC machined aluminium alloy spacer, and shimmed to a professional level to provide an exceptionally smooth running gearbox, with reduced friction, minimal noise from the gears, and a motor running smoothly without any additional stress caused by sub-optimal meshing and horizontal movement of the gears.
Prometheus EG Hard Bevel Gear - Heat Treated Japanese Steel
Improved Longevity - Reduced ARL Load - Click for more info
Strong gears are the core of any high performance Airsoft build, and while the ONYX retains most of the original Krytac hardened steel gears which are superb, the Bolster Team decided they could do better. Constructed from steel hardened using precision shot peening, the Prometheus EG Hard Bevel Gear is widely known as the strongest bevel gear on the market, and comes with the Prometheus pedigree.
The precision shot peening process essentially compresses the surface of the part and delays the formation of cracks and fractures by repeatedly shooting a spherical projectile at the object to be peened using compressed air and is a commonly used technique in the manufacture of military vehicles and aircraft to prevent fatigue cracks from developing in these high stress applications . Shot peening also helps prevent corrosion and adds wear resistance, and this is especially useful on a bevel gear as it is this gear which meshes with the motor and anti reversal latch and is most likely to come under sudden high strain.
Guarder Reinforced Tappet Plate - Reinforced Nylon Polymer
Highly Durable - Perfect Nozzle Alignment - Click for more info
The Guarder reinforced tappet plate has the reputation of being the best out there by the majority of Airsoft techs due to its durability and precise build which encourages perfect nozzle alignment. The tappet plate is constructed from reinforced nylon polymer which has the perfect amount of rigidity without being vulnerable to sudden fractures under heavy load as a conventional polycarbonate tappet might.
This part was chosen for the ONYX Revision 2 to add strength and give this essential part inside the best chance of withstanding the ultra-high rate of fire the ONYX platform provides.
Gate TITAN Drop in MOSFET V2 USB link Advanced Set
Improves efficiency - Provides pre-cocking function - Protects circuitry
Gate Electronics is well known amongst Airsofters for providing some of the best MOSFETs the Airsoft industry has to offer. These include the basic X-ASR which provides battery protection, the ASTER which adds GATE Control station App functionality, and the Gate's flagship option, the TITAN. The TITAN takes the already well equipped Bolster Armouries ONYX and transforms it from an extremely well tuned AEG into the realms of an advanced training weapon.
The TITAN provides a plethora of functions, including trigger travel adjustment, pre-cocking, Burst mode, Binary trigger, and adaptive active braking. A total of 8 optical sensors within the TITAN are used to track the movement of the gears, piston, and trigger to ensure the gears complete a full cycle with each trigger pull and the gears stop exactly where they should. The TITAN MOSFETs installed in the Bolster Armouries ONYX are pre-setup with the optimal settings for the platform and provide instantaneous trigger response and premium level functionality, including protection against over-discharge of your battery, short-circuits, and overheating.
Unlike other advanced MOSFETs, the TITAN has remarkably low power consumption and includes a "sleep mode" which activates when the ONYX has not been fired for some time. This protects your battery in the event that you forget to disconnect it after a skirmish, whilst other MOSFETS may drain the battery entirely over time, rendering the battery useless.
The settings programmed into the TITAN MOSFET by the Bolster Armouries tech team have been selected to provide the absolute optimum settings for the ONYX platform. The pre-set configuration includes pre-cocking set to medium speed for the best balance between prolonging the lifespan of the internals and providing the highly responsive trigger pre-cocking setups are known for.
Warhead Industries CNC Ultra High speed (M) Motor 36k RPM - CNC Machined 7075 Aluminium housing
Reduces heat build-up - Exceptionally high rate of fire - Electronic speed control
The motor is perhaps the most important part when it comes to providing extreme levels of performance in an Airsoft AEG, though with a faster motor comes the need to upgrade other internal components to prevent premature failure. In a home build, this often results in an "arms race" of parts so to speak, as whenever a part is upgraded it will require another part to be upgraded to prevent damage and maximize the AEGs potential.
The Bolster Armouries tech team is confident that their gearbox internals are the best available, and the only motor option that provides the speed, smooth running, and longevity to get the most out of the other enhanced parts would be the Warhead Industries Ultra High Speed motor. Known for their innovation and pushing the limits of Airsoft performance, Warhead Industries provide the best Airsoft motor around; utilizing the most up-to-date technology to provide a previously unheard of torque to weight ratio, and impressive heat dispersion.
The Warhead motor is housed inside a CNC machined 7075 aluminium shell with ribs machined in to reduce heat build-up within the motor, avoiding one of the primary causes of motor failure with their pioneering design. Utilizing "brushless" motor technology, the Warhead Ultra High Speed motor is considerably quieter than a standard motor, and uses superior quality Neodymium magnets combined with a hand-wound, temperature resistant copper stator wind to provide its incredible 36,000 revolutions per minute cyclic rate.
Conventional brushed motors suffer immensely from heat build-up when operated for more than 30 seconds continuously, due to the high internal friction generated. In a brushless motor, the main source of heat build-up is simply friction with the air which can be kept at a manageable level for far longer. With the Warhead motor installed, your trigger finger will get tired far sooner than your ONYX AEG will!
This motor also includes an Electronic Speed Control (ESC) module, which is hidden beneath a CNC machined aluminium cover at the base of the motor. This circuit controls and regulates the speed of the motor whilst providing low voltage cut-off and over-current-draw protection, providing an additional level of safety for your high performance Bolster Armouries ONYX.
For the skirmisher who is fed up with the expense and time commitment of chasing that ever-elusive perfect performance, or for a new player who wants to pick up a highly upgraded Airsoft AEG and get stuck in straight away with the best kit available, the ONYX SBR has it all covered. The Bolster Armouries team has done all the legwork, testing, troubleshooting, and setup, all you need to do is get out and shoot! You can do so with confidence due to the extended warranty and service package supplied with each Bolster Armouries RIF; if anything fails the Bolster team will see that it is resolved as a priority and have you ready to shoot again in no time!
The [Forged Edition] of the ONYX Platform builds on experience gleaned over a very successful first year of operation for the original ONYX AEGs, adding strengthened internals which have also been retrofitted to the previous ONYX AEGs, and some minor aesthetic and ergonomic tweaks to keep the ONYX at the cutting edge of Airsoft platform design.
This is the closest you will get to "pay to win" when Airsofting; the range, rate of fire and accuracy of the ONYX SBR are beyond any mass produced AEG we have ever seen, even surpassing some of our custom setups with years of work put into them. The Forged Edition makes things even better, adding strengthened parts to help extend the life of your ONYX, no matter how often you skirmish it! If you love having the upper hand and are happy to sport every advantage in game, the ONYX SBR is the only thing out there that will provide!

Joule Charts
Special Instructions
These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.
FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.
Tap the tabs below to open the relevant chart for your replica.
This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.
In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.
Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
