Delta Armory DA-A15 ALPHA™ 13" M-LOK M4/AR-15 AEG

Whether you are looking for a mid-length AR platform for woodland skirmishes or a base gun for your custom DMR build, the DA-A15 13" M-LOK M4/AR-15 AEG from Delta Armory is a solid choice. Equipped with an M-LOK handguard styled after the popular Strike handguard, a gunfighter mod.3 style pistol grip and the well-designed Delta Armory battery stock, the DA-A15 is dressed to impress on the outside and ready for any mission essential accessories you choose to add. 

Being an AEG of the Delta Armory ALPHA™ line, the DA-A10 is considerably pre-upgraded straight out of the box, boasting a reinforced 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. ALPHA™ line AEGs also boast full metal construction and the unique Delta Armory battery stock, making the DA-A15 perfect for those who want an elite look and realistic heft. 

Starting at the front, we can find a pre-installed birdcage flash hider concealing 14mm CCW male barrel threads beneath. This means you can add a tracer or suppressor as soon as you are ready, or an alternative muzzle device to customise the looks of the DA-A15. If you are going full DMR with your build, this thing is begging for a suppressor!  

Moving rearwards, we come to the M-LOK handguard of the DA-A15 which is constructed from aluminium using CNC machining, guaranteeing in-spec attachment slots and rails and a flawless form. The handguard is equipped with a short section of 20mm Picatinny rail at the receiver end, offering a lengthened receiver rail so you can mount larger optical sights and long eye relief LPVO scopes, perfect for DMR duty!

The sides and bottom of the handguard are adorned with M-LOK negative space attachment slots, allowing you to mount the latest vertical and angled foregrip designs directly or make use of 20mm Picatinny rail adapters for M-LOK if you prefer 20mm Picatinny accessories. The front end of the handguard is also aggressively styled with angled weight reduction/cooling vents, mimicking the real steel "Strike" style handguard. The benefit of a modern M-LOK handguard is that in its slick configuration, the handguard is incredibly light and surprisingly ergonomic, meaning you don't need to add rail covers to avoid the cheese grater effect as you might with a 20mm quad rail.

The receiver of Delta Armory's DA-A15 is a modernised design, complete with machined in gripping texture on the front of the magazine well, ideal for shooting from unconventional positions and angular surfaces across the receiver, giving the old '60s AR design a 21st-century facelift. The trigger guard is also enlarged and built into the receiver, improving strength considerably and following trends in the latest high-end real steel AR-15 rifles. Being an AEG of the ALPHA™ line, this receiver is constructed from alloy, matching the metal to polymer proportions of the real AR-15.

The fire selector is positioned just above the pistol grip and offers 3 modes of fire; SAFE, SEMI and AUTO, with a 90-degree throw between each mode. This makes the selector easy to switch, but not so easy that it can be knocked out of position accidentally. The magazine release is on the right side of the magazine well and is accessible for a right-handed user with the tip of the trigger finger.

Pulling back the charging handle, located at the top rear of the receiver will open the dust cover and retract the mock bolt carrier to allow access to the rotary HOP-up adjuster. This is the latest HOP-up unit design for the M4/AR-15 and provides finer increments of adjustment and holds its setting more effectively when compared to the older gear style HOP-up unit. The charging handle has an extended latch for easier access, allowing even those with thick gloves to access the HOP-up unit, though you may need to take off a glove to turn the adjuster!

The mock bolt catch is located in the centre of the left side of the receiver, and while this is a dummy control which doesn't provide a function it is nonetheless a separate part to maintain the realistic appearance and avoid the tell-tale signs of being a replica. The dummy forward assist is present on the right side of the upper receiver, right where it should be. This control does nothing on an AEG, and some real AR shooters argue it does nothing on the real thing, but it is included on the DA-A15 to keep the rifle faithful to real M4/AR-15 rifles.

The pistol grip of the DA-A15 boasts a refined grip angle for greater comfort when shooting with the stock fully collapsed and in more modern shooting stances. Based on the real steel "Gunfighter mod.3" grip, a modern ergonomic design, each flank of the pistol grip includes fine texturing for perfect wet weather handling. The trigger is known by Delta Armory as the CNC Type A Flat trigger, offering a flat serrated front surface with a short finger ledge, ideal for rapid double taps.

At the rear of the receiver, we come to the steel CQD style sling plate, which offers ambidextrous functionality with single-point slings; perfect for left or right-handed shooters. The steel construction of the sling plate practically guarantees even if you mount a massive rifle scope, PEQ box and RunCam, the sling plate will be strong enough to support the weight. Following the sling plate, we come to the good old AR buffer tube, constructed from alloy and offering 6 adjustment positions for the pre-installed stock, or any other M4/AR-15 AEG stock you choose to mount!

To the rear of the sling plate, we come to the M4/AR-15 buffer tube, which is constructed from alloy. The buffer tube offers 6 positions of stock adjustment for the pre-installed Delta Armory battery stock. To access the battery compartment, squeeze the two tabs at the toe of the stock together, after which you can lift the butt plate off, remove the battery plug, and make use of the stock's built-in battery compartment to house a nunchuck/crane-style battery. For the DA-A15, we recommend a 7.4V 1300mAh LiPo crane/nunchuck battery but you can also make use of a 9.6V 1600mAh NiMH for extra capacity.

As it comes, the DA-A15 is fitted with plenty of pre-upgraded internal parts focusing on longevity and user-friendly maintenance. The version 2 gearbox shell is reinforced, allowing it to be upgraded for higher power springs if you want to take your build in a DMR direction. The spring guide is a quick change example, allowing for quick and easy power tuning without opening the gearbox shell and has ball bearings in its base to reduce the rotational force applied to the gearbox shell for a longer lifespan. 

Inside the gearbox, we have 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 ball-bearing bushings allow the gears to spin more freely with a reduced gearbox report and a much smoother sound. To provide the accuracy needed to get the job done at long range, the DA-A15 ALPHA™ is rocking a 6.03mm tightbore inner barrel paired with a rotary HOP-up unit, offering higher FPS with the same spring and finer HOP-up adjustment increments. 

If you are working on a DMR build or you want a slick modernised AR at the cutting edge of external ergonomic features, the Delta Armory DA-A15 is one to watch. Equally at home with being upgraded as it is running straight out of the box, the DA-A15 is ideal for the woodland or urban skirmisher who needs a platform with superb long range performance and a stylish, modern aesthetic.
