Delta Armory Airsoft

If you're just starting your Airsoft journey and looking for an affordable lightweight polymer build M4/AR-15 AEG with programmable fire controls, the Delta Armory DA-C05-EGL CHARLIE™ Silent Ops 7 M4/AR-15 AEG is what you need. This M4/AR-15 AEG boasts the latest MOSFET/ETU system from Delta Armory, known as the EAGLE™.

The internals of the DA-C05-EGL are similar to the original CHARLIE™ series, but the EAGLE™ ETU adds a whole new level of functionality. Using only the trigger and fire selector of the gun itself, you can program the EAGLE™ for burst modes of various duration, binary trigger, sniper delay, semi-auto only, AUG mode, pre-cocking, trigger sensitivity and active braking, giving you an incredibly advanced primary, for an entry-level price!

For those seeking a lightweight, yet advanced starter AEG with reinforced internal parts and full compatibility with aftermarket M4/AR-15 AEG upgrades, the Delta Armory DA-C05-EGL CHARLIE™ Silent Ops 7 M4/AR-15 AEG is one to watch!

Whether you're new to the game and looking to start out with a full metal platform bristling with advanced features or a veteran skirmisher in search of an M4 AEG you can just pick up and go with, the Delta Armory DA-A06-EGL ALPHA™ KeyMod 10" M4/AR-15 AEG is a fine choice. A realistically hefty full metal build with a cutting-edge aesthetic at just the right length to do its dirty work both outdoors and in CQB, the DA-A06-EGL is ready for any challenge that faces it. 

Equipped with a KeyMod handguard, sound-amplifying muzzle device and modernised receiver on the outside and kitted out with SHS reinforced parts, a 6.03mm tightbore inner barrel and the EAGLE™ programmable MOSFET on the inside, the DA-A06-EGL is an extremely competitive platform, both on price and in game! The EAGLE™ allows you to enhance trigger response with pre-cocking for CQB or select burst mode, binary trigger or AUG mode to improve hit probability outdoors, with the additional option of locking the gearbox to semi-auto only for DMR duty. 

If you're after a new M4 AEG but don't like to commit to a particular build direction, the DA-A06-EGL won't make any decisions for you! Thanks to the "Barbie for men" modularity of the AR platform and the highly flexible EAGLE™ ETU, the DA-A06-EGL ALPHA™ KeyMod 10" M4/AR-15 AEG is ready to accept a full compliment of accessories, be kitted out just how you like it and give the enemy team what for when it comes to skirmish day!

If you prefer shorter AR platforms and want something full metal with a programmable MOSFET, the Delta Armory DA-A13-EGL ALPHA™ 8" M-LOK M4/AR-15 AEG is one of the best options out there. Equipped with an M-LOK handguard constructed from CNC machined aluminium, the unique Delta Armory receiver, an ergonomic pistol grip and a pre-installed aluminium angled foregrip, you have little left to do on the outside other than add your favourite optic!

Inside, we're also remarkably well-equipped! Inside, we have a reinforced V2 gearbox shell, SHS piston with a full steel tooth rack, a quick change ball bearing spring guide and a 6.03mm tightbore inner barrel paired with a rotary HOP-up unit, giving you impressive performance and advanced features for a respectable price point. Also present inside is the Delta Armory EAGLE™ programmable MOSFET/ETU, a serious game changer!

With the EAGLE™ ETU, you can program the fire controls for burst modes of various durations, binary trigger, sniper delay, semi-auto only, AUG mode, pre-cocking, trigger sensitivity and active braking using only the trigger and fire selector of the gun itself. The result is an incredibly advanced M4 AEG with almost unlimited flexibility via the advanced EAGLE™ ETU and full compatibility with aftermarket upgrades for those who want more. If you like your ARs as cutting edge on the inside as they are externally, the Delta Armory DA-A13-EGL ALPHA™ 8" M-LOK M4/AR-15 AEG should suit you perfectly!

If a DMR is on the cards, the Delta Armory DA-A20-EGL ALPHA™ TEMPEST 2 M4/AR-15 AEG is a fantastic choice on which to base your build! Boasting full metal construction and plenty of pre-upgraded internal parts, this M4/AR-15 AEG platform is rocking a lengthy 16-inch outer barrel, giving it the appropriate looks to suit a DMR build.

To make matters all the sweeter, the inner barrel is a 6.03mm tightbore measuring 420mm in length and the pre-installed EAGLE MOSFET allows you to program the trigger for semi-automatic only. Coupled with its quick-change spring system, the TEMPEST 2 is probably one of the easiest DMR conversions out there! Amongst the EAGLE's other tricks, we have the option to use burst modes of various durations, binary trigger, sniper delay, AUG mode, pre-cocking, trigger sensitivity and active braking.

For any long-range oriented build, the DA-A20-EGL ALPHA™ TEMPEST 2 M4/AR-15 AEG would make a fantastic starting point but is already very well equipped to compete as it comes. If you're seeking a longer platform for outdoors work and want some advanced features thrown in for a remarkable price, the TEMPEST 2 is your best bet!

If you're looking for a sniper rifle with more than its fair share of robust internal components, the Delta Armory M24 R700 Spring Bolt Action Sniper Rifle is a fine choice. Externally based on the real steel M24 sniper rifle hybridized with the R700 sporting rifle, Delta's M24 is designed for mobility, keeping weight to an absolute minimum and trimming off any unnecessary frills which add more weight than their worth.

Inside, we are equipped with a CNC Steel cylinder, CNC aluminium piston, 90-degree sear and CNC steel spring guide, giving you the parts you need to keep the M24 running in the long run and avoiding the usual affordable sniper rifle hurdle of whacking a super strong spring into a platform that isn't ready for it. Though the M24 may use its own unique internal system, the HOP-up rubber is compatible with aftermarket VSR/GBB rubbers so the upgrade fiends can get their fix. If you want to sample sniping but don't want to get in too deep with an expensive primary, the Delta Armory M24 R700 Spring Bolt Action Sniper Rifle is a fantastic option!

If you're looking for a highly flexible, full metal M4/AR-15 platform, the Delta Armory DA-A19-EGL ALPHA™ TEMPEST 1 M4/AR-15 AEG should suit you perfectly! Kitted out with Delta's ALPHA line externals with the unique billet-style receiver and an SMR-style handguard up front, this M4 doesn't look like anything else out there, and the perks don't end there!

Inside, you'll find a 6.03mm tightbore measuring 380mm in length, a set of 18:1 ratio steel gears mounted on 8mm ball bearing bushings, an SHS piston with a full steel tooth rack and an SHS delayer chip and tappet plate to add reinforcement in the key places that need it. 

The pre-installed EAGLE MOSFET allows you to program the trigger for semi-automatic only, burst mode, binary trigger, AUG mode and sniper delay. Coupled with its quick-change spring system, the TEMPEST 1 makes for a great DMR base gun thanks to its relatible easy conversion process. Whether you're looking for an all-rounder for both indoor and outdoor environments or you want to quickly switch between a DMR setup and standard AEG, the Delta Armory DA-A19-EGL ALPHA™ TEMPEST 1 M4/AR-15 AEG will be an asset to you!

If you have mid-caps to load, you'll need one of these! The Delta Armory 100rnd Magazine Speed Loader is a thumb plunger type speed loader constructed from translucent polymer which holds 100 BBs approximately. The loader is filled via its fill window at the top and the thumb plunger can be deployed and stowed via the button on the side. 

To load an Airsoft mid-cap or low-cap, simply fill your speed loader, align the fill/feed port of the magazine with the aperture on the bottom of the loader, hold the mag and loader together and push the thumb plunger repeatedly until it becomes firm. Your mag is now filled. If you run mid-caps, low-caps or you like to use multiple weights of BB, speed loaders are essential Airsoft kit!

If you need BBs for outdoor skirmishes, 0.28g BBs are what you need! The Delta Armory 0.28g Diamond 6mm BBs are supplied in a 1KG resealable bag of 3571 BBs approximately and are high-grade polished BBs to ensure reliable feeding and maximum accuracy potential. 

If you're in search of a cheap red dot sight with a wide field of view, the Delta Armory 1x30 Red Dot Sight is exactly that. Boasting an integral 20mm Picatinny mount, 5 brightness settings with either a red or green dot and a whopping 30mm objective lens, this red dot sight is ready to mount and cheap as chips, even packaged with a CR2032 3V Button cell to get you up and running straight out of the box. 

If you're looking for accuracy improvements for your M4/AR-15 AEG, the Delta Armory TRINITY R-Hop Bucking Bundle for AEG is what you need to tighten your groupings. This set includes an enhanced HOP-up arm, HOP-up bucking and OMEGA-style nub manufactured for Delta by upgrade legends Psionic Upgrades. The included HOP-up arm is designed for M4/AR-15 AEG rotary HOP-up units, specifically the Delta Armory/Specna Arms/Evolution/Lancer Tactical type but the bucking and nub are compatible with other Airsoft AEGs of all different shapes and sizes. 

The inner patch of the TRINITY bucking is diamond-shaped, similar to the Maple Leaf Super bucking, intended to improve accuracy by applying backspin more consistently. The advantage of using a TRINITY set rather than doing all the mods yourself is its simple drop-in installation, low price compared to sourcing a separate bucking, nub and HOP-up arm and guaranteed compatibility, meaning no chance your nub doesn't work with your chosen bucking. If you're looking for tighter groupings from your Airsoft AEG, the TRINITY R-HOP Bucking Bundle is the one to go for!

If you play a lot of CQB, a tactical flashlight will be an asset to your setup. The Delta Armory Defender Shield Tactical Flashlight is a highly flexible unit capable of being used as a handheld light or weapon light, packaged with a pressure switch tail cap and equipped with a push button tail cap as it comes. Also included is a 20mm Picatinny ring mount to allow you to mount it to your primary and a lanyard so you can carry it as a handheld light and avoid dropping it in wet weather.

The Defender Shield is powered by the included rechargeable18650 Lithium battery but the charger is not included. Compatible chargers can be found by putting "18650 Battery Charger" into your favourite search engine. If you're kitting out your primary for CQB or night skirmishes you need this on your primary!

If you need biodegradable BBs for your pistol or shotgun, the 0.20g Diamond 6mm BIO BB from Delta Armory is a fantastic choice. Supplied in a resealable bag of 5000, Delta's Diamond BBs are high-grade polished 6mm BBs with tight tolerances to ensure reliable feeding and maximum accuracy potential.

Whether you are working on a military-style build or want a red dot sight with a uniquely tough exterior, the Delta Armory Holo-552 Style Red Dot Sight is well suited to your needs. Constructed from aluminium with an integrated 20mm Picatinny rail mount, the Holo-552 is ready to be mounted on any Airsoft gun with a 20mm Picatinny top rail and is set at the perfect height for use with a flip-to-side magnifier. 

Offering the iconic multi-function reticle matching the real thing perfectly with a choice of red or green colour options via the "NV" button, the Holo-552 allows you to shoot fast up close using only the outer ring of the reticle or take precise shots using either of the two central dots at longer ranges. Reticle brightness is fully adjustable, with 5 settings for each colour so you can set it perfectly for the ambient lighting conditions. If your next attachment is going to be a red dot and you appreciate the military styling of the iconic Holographic Sight, the Holo-552 from Delta Armory is a fine choice!

If you need a platform for dealing with foes at range, the DA-A15 ALPHA™ is the right tool for the job. This Delta Armory AEG boasts full metal construction and a selection of pre-upgraded internals, including a 6.03mm tightbore inner barrel, rotary HOP-up unit and an upgraded piston, delayer chip and tappet plate from SHS. 

On the outside, we are treated to an M-LOK handguard styled after the popular Strike rail system, a unique Delta Armory receiver featuring a built-in enlarged trigger guard and magazine well gripping texture along with the simply awesome Delta Armory battery stock, to name but a few of the slick ergonomic features of the platform. If you need a longer platform for a DMR build or woodland warfare, the DA-A15 is a sure hit if you are into modern ARs!

If you're putting together an M4/AR-15 AEG from scratch or you want to add a sliding stock to your fixed stock rifle, this buffer tube should help! The Buffer Tube for M4/AR-15 AEG from Delta Armory is constructed from alloy and compatible with most M4/AR-15 AEGs on the market. The tube provides 6 positions of adjustment for whichever M4/AR-15 AEG sliding stock you choose to mount, allowing you to collapse the stock for storage or close-range engagements. 

The set includes the buffer tube itself, the castle nut (non-functional) and the bolt required to mount the buffer tube. This is a standard TM clone buffer tube design and should fit most M4/AR-15 AEGs without issue, though as with any external mod, there may be slight fitting which needs to be carried out. 

If you are working on your Special Forces loadout but you haven't had time to hit the gym, Delta Armory has the MK18 for you! The DA-B15-ETU BRAVO™ is styled to match the real MK18 MOD.1 rifle issued to US Navy SEALs and Delta Force but is far lighter and handier than full metal versions thanks to its combination of a CNC aluminium handguard and alloy outer barrel with a high density polymer receiver and buffer tube. 

Inside, this MK18 MOD.1 is rather special, being fully upgraded internally with little room for more. Inside, we are treated to a plethora of CNC machined aluminium parts, CNC steel 16:1 gears, a high torque motor and a programmable ETU/MOSFET system to keep it all in check. The ETU also allows for burst mode and binary trigger to be programmed in, along with pre-cocking for an almost instantaneous trigger response. If you want the looks of the MK18 without the weight, the DA-B15-ETU BRAVO™ brings the MK18 styling along with incredible performance!

If you're looking for a compact AR platform with more than its fair share of perks, look no further than the Delta Armory DA-A13-ETU ALPHA™. This AEG is at the very top of Delta Armory's range, boasting the full metal external build of the ALPHA™ series paired with the ETU series internals, resulting in a beast of a platform, both inside and out.

Equipped with an M-LOK handguard constructed from CNC machined aluminium, the unique Delta Armory receiver, an ergonomic pistol grip based on the gunfighter mod.3 grip and a pre-installed aluminium angled foregrip, you have little left to do on the outside other than add your favourite optic!

The news is similarly impressive inside! The version 2 gearbox has a reinforced shell, CNC aluminium piston and cylinder heads, CNC steel 16:1 gears running on 7mm ball bearing bushings and a high torque neodymium magnet motor to deliver the torque needed for a lightning-fast trigger response. The barrel is a 6.03mm tightbore paired with a rotary HOP-up unit, granting this compact PDW-esque AR surprising long range performance. A programmable ETU/MOSFET system improves electrical efficiency and allows for burst mode, binary trigger and pre-cocking to be programmed in using the fire controls of the AEG itself. If you don't want the fuss, troubleshooting and tuning that comes with upgrading your own beast of an AEG, no need to put yourself through that, Delta Armory has done it for you!

If you are keeping your eye out for a base for your dream DMR build and have a certain sneaky playstyle, the DA-A10 ALPHA™ Silent Ops DMR should fit you like a glove. This M4/AR-15 platform is part of Delta Armory's ALPHA™ line, top of the range when it comes to externals and boasting more than its fair share of pre-upgraded internal parts as a bonus!

Inside, you will find a reinforced V2 gearbox shell, SHS piston with a full steel tooth rack, a quick change ball bearing spring guide and a 6.03mm tightbore inner barrel paired with a rotary HOP-up unit for impressive long-range effectiveness. The quick change spring makes for a relatively easy DMR upgrade, meaning if you want the DA-A10 to live up to its name you'll have a much easier time of it! 

Whether you want a stealthily styled AR platform for mid to long range engagements or you're working on a suppressed DMR build, the DA-A10 ALPHA™ Silent Ops DMR already has the aesthetic and the upgraded internals; all it needs is pointing in the right direction!

If you're building a DMR or accurised AEG, the Delta Armory BERSERKER R-Hop Bucking Bundle for AEG is what you need to achieve maximum range. This set includes an enhanced HOP-up arm, HOP-up bucking and OMEGA-style nub manufactured for Delta by upgrade legends Psionic Upgrades. The included HOP-up arm is designed for M4/AR-15 AEG rotary HOP-up units, specifically the Delta Armory/Specna Arms/Evolution/Lancer Tactical type but the bucking and nub are compatible with other Airsoft AEGs of all different shapes and sizes. 

The inner patch of the BERSERKER bucking is shaped to fill the HOP-up window on your barrel, just like home-brewed R-HOP setups of old. The advantage of using a BERSERKER set rather than doing all the mods yourself is its simple drop-in installation, low price compared to sourcing a separate bucking, nub and HOP-up arm and guaranteed compatibility, meaning no chance your nub doesn't work with your chosen bucking. If you use heavy BBs and need a range increase, this set will do exactly that!
