The VULKAN Advanced AK AEG is Bolster Armouries' first AK platform, hand-tuned to perfection by talented technicians following the Bolster philosophy that only perfection is good enough. Named for its significant weight and enduring majority steel build, VULKAN is the English pronunciation for "вулкан", the Russian word for "Volcano"; an eternal immutable barrier which prevents any enemy force from advancing without enduring a blazing burst of peak performance.

The base platform is the LCT LCK104 AEG, a platform known to provide one of the most realistic AK handling experiences out there, bristling with steel and stamped steel parts front-to-back. The only internal parts which remain are the gearbox shell, HOP-up unit and nozzle; everything else has been replaced with the best aftermarket upgrade parts out there and even some unique parts commissioned by Bolster Armouries, resulting in an incredible AK platform which can go toe to toe with the ONYX Advanced M4 AEG any day of the week.

Formed using the absolute best external parts on the market with the prerequisite potency only a Bolster Armouries AEG can provide, the VULKAN marries the enduring AK build format with a vigorously aggressive modern style-up with its authentic Magpul Zhukov-U M-LOK Handguard and MOE Carbine Stock. The LCT Stamped Steel Railed Receiver Top Cover was added for optical sight compatibility and the monstrously menacing 5KU DTK-2 Muzzle Brake completes the ferocious front end.

Inside, you'll find the best internal parts selected through the Bolster Armouries R&D process. The Gate TITAN V3 MOSFET equipped with its Expert Firmware gives this caveman-simple AK rifle intelligent functionality, offering a vast range of programmable customisation options via the Gate Control Station app. The original TITAN™ V2 is still performing flawlessly in our first batch of ONYX AEGs released nearly 3 years ago; newer MOSFETs have since been released but the proven TITAN's pedigree and reputation are yet to be matched.

After extensive work separating the wheat from the chaff when it comes to aftermarket upgrades for AK AEGs, the talented technicians of Bolster Armouries selected parts from FPS Softair, Laylax/Prometheus, Maple Leaf, Lonex and Retro Arms to form the foundations of the VULKAN, driven by the earth-shattering Warhead Industries CNC Black Brushless Motor. The result is an AK AEG at the top of its game both internally and externally, ready to outshoot almost anything else you'll encounter on the skirmishfield.

If the mass-produced AK replicas from other manufacturers are the equivalent of a Lada, the Bolster Armouries VULKAN is a GAZ Tigr; built for the rigours of combat and styled to match, providing a steadfast surge of pure performance with a uniquely intimidating aesthetic.

Bolster Armouries VULKAN Advanced AK AEG

A new addition to the Bolster Armouries lineup, the VULKAN Advanced AK AEG is based around the LCT LCK104 AEG, an AK-104 replica made almost entirely from steel; the only way to do the real Avtomat Kalashnikova justice in Airsoft form. The AK-104/105 is widely regarded as the best-looking AK, landing right between the full-length AK-74 and the more compact AKS-74U configurations in length and Bolster Armouries has made it even more handsome with authentic Magpul furniture and Western-inspired ergonomic enhancements.

Every part made from steel in a real AK rifle is also steel in the VULKAN, including the barrel, front sight/gas block assembly, gas tube, handguard caps, trunnion block, receiver, trigger guard, fire selector, dust cover and stock tangs. Make no mistake, this is not your everyday "full metal" AK AEG; the vast quantities of milled, cast and stamped steel parts give the VULKAN realistic weight distribution and unsurpassed structural strength. When you get your hands on the VULKAN, you'll realise how it got its name!

The muzzle device chosen for the VULKAN is a fantastic replica of the real steel DTK-2 muzzle brake made by 5KU, constructed from steel and finished in a dark metallic gunmetal grey. The DTK-2's squat, sinister form gives the VULKAN an aura of intensity unmatched by the original AK-104 muzzle brake and the Russian origin of its design suits the East/West crossover theme of the build perfectly. The DTK-2 mounts to the steel outer barrel's 24mm CW Russian threading, meaning if you want to run the VULKAN suppressed or with a tracer, you can do so provided you source a device with the correct thread or use a 14mm CCW thread adapter. We recommend the LCT ZDTK-T PUTNIK to maintain the brutal Russian aesthetic.

The steel gas block/front sight assembly follows just behind, finished with an anti-corrosion coating matching real Russian AK rifles perfectly. The coating adds another level of contrast and visual interest to the externals, making the details stand out for the discerning observer. The mock gas tube follows just behind, constructed from stamped steel with a gloss black finish; a perfect match for real AK gas tubes. Real firearms rarely have a consistent finish across all parts due to different manufacturing methods and design parameters; LCT did a fantastic job replicating this on the LCK104, making it the perfect base for the beastly VULKAN.

One of the highlights of the build is the handguard setup, an authentic Magpul Zhukov-U handguard with M-LOK negative space attachment slots and a ported upper handguard made from Magpul's proprietary glass-fibre reinforced polymer. M-LOK slots are available at the front and rear on either side, ideally placed for tactical flashlights and laser aiming devices with an additional 4 slots running along the bottom, ready for your choice of vertical or angled foregrip.

In line with the positively slick Magpul aesthetic with its ribbed design, built-in hand stop at the front and dynamic yet smooth ergonomic profile, the Zhukov-U is modern and menacing in equal measure; a perfect fit for the VULKAN build objectives and a significant handling improvement when compared to the original handguard.

The milled steel trunnion block protrudes just to the rear of the upper handguard, another point of intricate contrast in the VULKAN external design. Just like a real AK, the machining marks are visible through the gunmetal grey finish and stand out nicely alongside the disassembly lever which has a similar finish to the gas block, mimicking real steel anti-corrosion finishes.

Replacing the rear iron sight of a standard AK, we have the LCT Stamped Steel Railed Top Cover, a hinged design which connects to the trunnion block where the old-school tangent rear sight would be on the original LCK104. The top cover is constructed from thick stamped steel and features a CNC-machined aluminium 20mm Picatinny rail riveted onto its upper surface, ready for your choice of optical sight. The rail slots are numerically marked so you can track your optic placement when removed for maintenance and the rail as a whole is flawlessly machined, guaranteeing solid mounting with whichever 20mm Picatinny compatible sighting system you choose.

The hinged top cover is extremely convenient compared to standard AKs when it comes to battery installation; simply press the button at the rear of the top cover and it will hinge open under spring tension. Inside, you'll find a Deans/T-Plug battery connector to which you connect your battery. We recommend an 11.1V 20C LiPo battery in AK stick configuration, one of which is included in the VULKAN package.

The receiver is a flawless replica of the real thing, constructed using thick steel stamped and folded into shape, with rivets in all the right spots and authentic recessed Cyrillic lettering surrounding the fire selector switch. The selector switch itself is a great replica of the real steel X47 enhanced selector switch, allowing you to switch modes easily from a firing grip; an attribute the original AK platform lacked. The X47 selector also includes a cutout along the top, designed to allow a real steel AK bolt carrier to be locked open for malfunction clearance.

On the bottom of the receiver, we can find the magazine release/trigger guard assembly, made from steel and centrally positioned, ideal for left or right-handed shooters. The trigger guard assembly is all original LCT but the trigger is something else. The team chose the RetroArms CNC AK Trigger finished in metallic red to add an eye-catching hint to onlookers that this AK is as premium on the inside as it is externally. The RetroArms CNC trigger is paired with a bespoke part commissioned by Bolster Armouries, known as the AK Trigger Restrictor. This shortens the trigger travel to a minimum to facilitate rapid double taps and keep pace with previous Bolster AR platform releases.

At the rear of the receiver, we can find steel stock tangs, God's gift to the AK AEG user who likes to play rough. Stock tangs on most Airsoft AKs are constructed from alloy and are a known failure point, especially if the platform is dropped on the stock. While we don't advise throwing such a gorgeous AK around, the VULKAN is strong enough to resist all but the most extreme impacts thanks to the well-chosen LCK104 base platform.

Mounted to the stock tangs, we have the LCT AR Buffer tube, constructed from aluminium with QD sling sockets on either side, ready for QD sling swivels. The buffer tube provides 4 length of pull positions, allowing you to adjust the stock to suit your body type, stance and loadout perfectly.

Riding on the buffer tube, we are treated to an authentic Magpul MOE® AR-15 Carbine stock, a simplified derivative of the legendary CTR stock. An A-frame design equipped with sling slots aka "footman loops", the MOE® stock is a low-snag shape with a concealed adjustment lever and a rubber butt plate, offering ample traction for wet weather use and almost no chance of sling or rig-related snagging. The MOE® stock is made from the same robust polymer formula as the Zhukov-U handguard, promising the incredible strength and rigidity expected of a proven real steel stock design.

Real Steel Magpul Furniture

Magpul Industries Corp was founded in 1999 with its namesake product, the "Magpul", a magazine assist device designed to improve magazine handling under stress and in combative environments.

Fast forward a couple of decades and Magpul has become a household name in the tactical community, offering a vast range of innovative yet simple accessories for a wide selection of firearms. Magpul has always been Bolster Armouries' first choice when it comes to real steel accessories thanks not only to its seriously slick looks but also its mould-breaking concepts which have changed the game when it comes to platform ergonomics.

Magpul Zhukov-U M-LOK Handguard

The Magpul Zhukov-U handguard is the mid-length option from Magpul’s AK lineup, being the ideal length to be paired with the 12.5-inch barrelled VULKAN Advanced AK AEG. Made from some of the strongest polymer on Earth proven through years of use in both combat and training applications, the Zhukov-U is well up to the task of surviving the rigours of Airsoft skirmishing indefinitely under normal use.

With a dynamic, swept-back front end and built-in hand stop, the Zhukov-U is shaped for flawless ergonomics and includes ribs along its length to promote intuitive handling in all weather conditions. Styling-wise, the Zhukov-U looks like the AR-15 MOE handguard’s brutal, bad-boy brother, carrying over the iconic Magpul looks to the AK platform and matching its utilitarian, means business aesthetic.

The Zhukov-U is equipped with M-LOK attachment slots at the front on each side in the perfect spot for a tactical flashlight or laser aiming module. An additional slot is present at the rear, ideally suited to an M-LOK sling point. Running along the bottom, we have a row of 4 M-LOK slots, giving you plenty of space to mount a vertical or angled foregrip where you see fit.

Its mix of sleek styling when run slick with the ability to add M-LOK accessories to suit the mission at hand made the Zhukov-U the perfect fit for the VULKAN Advanced AK, avoiding adding excess mass to the already monstrous base platform while providing accessory interfaces to suit the modern battlefield.

Magpul MOE® AR-15 Carbine Stock

Based on the Magpul CTR Stock, the MOE is an "A-frame" design, intended to keep the weight of the stock to a minimum whilst retaining optimal strength. The adjustment latch is concealed within the A-frame shape, avoiding snagging on slings or other equipment while keeping the latch shielded against inadvertent activation. A premium chrome-silicone lock spring is used in the adjustment mechanism to provide dependable locking and a long life of repeated, reliable use.

Like its daddy, the CTR, the MOE is compatible with aftermarket CTR and MOE cheek risers from Magpul along with the Larue RISR, giving you the option to raise the comb height to suit whatever optical sight setup you choose. The pre-installed butt pad is constructed from 0.3" thick rubber for optimal wet weather traction but this can be replaced with an aftermarket CTR/MOE compatible butt plate at your discretion.

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 MOE stock include 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. Naturally, the MOE stock is made from the same ultra-strong Magpul proprietary polymer as the Zhukov-U handguard, giving you modern furniture easily strong enough to suit the VULKAN’s mountainous mass.

External Enhancements

While the classic AK look is iconic, the VULKAN needed some significant changes in ergonomics to keep it competitive with the ONYX and ONYX [Blackout] platforms on the field. Several aesthetic changes were made to suit the modern build style and the result is an AK at the top of its game, both outside and in.

Evike Matrix Ribbed Ergonomic Pistol Grip - High density Polymer

One of the biggest ergonomic pitfalls of the original AK design is the pistol grip, a product of an era before ergonomics were a consideration in rifle design. As such, the Bolster team replaced the original LCT AK-style pistol grip with a modern alternative, known as the Matrix Ribbed Ergonomic Pistol Grip.

The Matrix grip is shaped similarly to popular real steel ergonomic grips for AK rifles, equipped with linear ribs on the front and rear to add traction and recesses on either side for indexing the thumb. The back strap provides a smooth transition between the grip itself and the receiver, ensuring "hot spots" are minimised to reduce hand fatigue over long durations of use. Aesthetically, the Matrix Ribbed Ergonomic Pistol grip is a great match for the authentic Magpul parts, tying the full VULKAN build together as a completed piece.

LCT AR Buffer Tube for LCT AK Rifles - Aluminium

Constructed from aluminium with QD sling sockets on either side, the LCT AR Buffer Tube adds a touch of modernity to the ageing AK design. The buffer tube mounts to the steel stock tangs, offering 4 positions of adjustment for the authentic Magpul MOE AR-15 Carbine Stock. Being compatible with AR-15 stocks for mil-spec buffer tubes also means if you want to change up the looks of the VULKAN in the future, swapping the stock can be done in seconds.

The length of pull adjustment provided by the buffer tube means you can set the stock to suit your preferred stance and body type, using the more compressed positions for shooting with a plate carrier or body armour vest. QD sling sockets are a great addition, allowing you to mount a QD sling swivel on either side of the VULKAN and run a single-point sling, or add an extra sling point up front for a two-point sling setup.

LCT AK Railed Top Cover - Stamped Steel

Everyone who owns an AK replica knows they can be a bit of a handful when it comes to mounting optics; thankfully, the VULKAN has cleared this hurdle thanks to its LCT AK Railed Top Cover. The top cover is constructed from thick stamped steel with a CNC aluminium 20mm Picatinny rail riveted to the top, ready for your choice of optical sight.

Being a hinged design means convenience when it comes to battery swaps and also helps ensure the top cover fits tightly, avoiding the usual rattly AK top cover which definitely is not conducive to a precisely zeroed optic. The top cover of the VULKAN is absolutely rock solid; whether you opt for a red dot sight or magnified optic, your zero will stay true.

LCT ZRP-1 Charging Handle - CNC Aluminium

Inspired by popular upgrades found on real steel tactical AK builds in US civilian hands, the ZRP-1 Charging handle is a CNC machined aluminium extension mounting to the integral charging handle of the steel LCK104 bolt carrier, providing improved traction for wet weather use.

The ZRP-1 also extends slightly further from the receiver than the original handle, allowing modern AK manipulation methods such as racking the charging handle with the off-hand by going under the receiver to be carried out more intuitively. In terms of Airsoft, this is more of an aesthetic upgrade than anything else, but does make accessing the HOP-up unit that bit easier in a mid-skirmish downpour or when wearing gloves.

LCT X47 Selector Switch - Stamped Steel

LCT's X47 selector switch is based on real enhanced AK selector switches conceived for the US civilian tactical community, allowing Western handling techniques to be used with the pre-Cold War AK design. Constructed from the same thick stamped steel as the other LCT core parts, the X47 features a finger ledge to allow fire mode selection using the trigger finger while your strong hand remains on the pistol grip, ready to unleash hell.

A subtle change though this may be, an enhanced selector switch makes a massive difference in function for those who play "sights off, safety off" and is an iconic part of practically all modernised "tactical" AK builds in the real world. Also present is a cutout which allows the bolt carrier to be locked open in the real thing, but this is non-functional when it comes to the VULKAN and included purely for that tactical aesthetic.

5KU DTK-2 Muzzle Brake - Steel

While the AK-104 Trumpet Gas Booster muzzle brake is an iconic part of the original AK-104 build, it simply didn't look right on the dressed-to-impress VULKAN. The team opted for the 5KU DTK-2 Muzzle Brake, a fantastic replica of the real steel Zenitco DTK-2 seen on customised AK rifles from around the world.

A squat design with a pair of massive ports on each side and two smaller ports on the bottom, the DTK-2 is a seriously mean muzzle device constructed from steel and flawlessly machined. The real DTK-2 device is designed to reduce felt recoil and compensate for muzzle climb and is generally seen on carbine and SBR-length AK rifles, a perfect fit for the VULKAN.

Internal Enhancements

The internal parts present in the Bolster Armouries VULKAN are hand-selected for the high quality materials used in their construction as well as for their exceptional performance when installed properly. Each Bolster Armouries Gearbox is hand-built, with each gear being perfectly shimmed for smooth operation and the piston position 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 tightbore inner barrels out there, renowned for its rigidity and high quality internal finish. This is paired with the Maple Leaf OMEGA nub and Prometheus Purple HOP-up rubber, a combination which has performed superbly in previous Bolster Armouries AEG releases, reaching out to 60 meters and beyond in its stride. Let's have a closer look at what goes into a VULKAN, and why these parts are so noteworthy:
