Description

If you're looking for a highly flexible platform for an unbeatable price, the Delta Armory DA-C04-EGL CHARLIE™ 10" KeyMod M4/AR-15 AEG is worthy of your scrutiny! This Delta Armory CHARLIE™ line AEG boasts the cutting edge EAGLE™ programmable MOSFET and solid high density polymer construction for a lightweight and agile build with an alloy outer barrel to add strength where needed. 

Externally, the DA-C04-EGL is one of the more exciting CHARLIE™ line offerings, equipped with a mock KeyMod handguard to give it an elite look, further reduce weight and allow the included 20mm rail sections to be positioned wherever you need your accessories mounted. At the rear, we are equipped with the latest Delta Armory stock only present on the -EGL and FREYA™ series with a new ergonomic pistol grip with a more vertical angle, ideal for modern shooting stances. 

Inside, the new EAGLE™ ETU/MOSFET is the star of the show, offering unprecedented programming options using only the fire controls of the AEG itself. Options include 3 or 5-round burst mode, binary trigger, sniper delay, AUG mode, semi-auto only and precocking. Thanks to its quick change spring system, the DA-C04-EGL can be an assault rifle one day and a DMR the next!

Starting at the tip of the alloy outer barrel we can find an alloy birdcage flash hider, which mounts to the 14mm CCW male threads. The birdcage gives the DA-C04-EGL the classic M4/AR-15 look, but can easily be swapped out for a muzzle brake for a more custom style, a tracer unit for come CQB action or a suppressor if you have more of a sneaky play style.

Surrounding the outer barrel we have the polymer mock KeyMod handguard, which is styled after the KAC URX4 and gives the rifle a dynamic, high speed look. The mock KeyMod attachment interface is still functional, and allows the 3 included rail sections to be moved around and mounted anywhere at the 3, 6 or 9 o'clock position on the handguard, though the mock KeyMod slots are not compatible with aftermarket KeyMod accessories.

The 12 o'clock position provides a full length 20mm Picatinny rail which integrates seamlessly with the receiver rail to allow for longer optical sights to be used or red dot sight magnifier combos. As it arrives, the DA-C04-EGL is equipped with a pair of flip-up aperture iron sights, both of which are fully adjustable for windage and elevation. The sights can be deployed by pressing the textured tabs on each, which will snap the sights into position under spring pressure. To stow the sights, simply push them back down and they will lock into place.

Moving rearward we reach the receiver, which is a familiar M4/AR-15 layout and is constructed from high density polymer with a matt black finish. The fire selector is located on the left side of the AEG and sits directly above the pistol grip to provide fast and easy access for right-handed shooters. The fire selector has a 90-degree throw between modes, making it quick to operate but not too easy to accidentally knock it and end up in the wrong fire mode. 

Each fire mode is indicated with recessed markings reading SAFE-SEMI-AUTO. Being equipped with the EAGLE™ MOSFET, you can also lock off full auto and use the DA-C04-EGL as a DMR, set up for burst mode or binary trigger to improve hit probability or select pre-cocking to enhance your trigger response, all done using a combination of trigger pulls and fire selector movement. 

At the centre of the left side of the receiver, we can find a dummy bolt release catch which doesn't have a function in an Airsoft AEG but is included to keep the externals looking realistic. The bolt release is a separate part which is a nice touch to avoid the tell-tale signs that this is an Airsoft gun and not the real deal. Over on the right side of the receiver, we can see what is known as the forward assist button, located on the upper receiver behind the mock shell deflector. This button also has no function but serves to force the real M4/AR-15 bolt carrier into battery if it fails to close due to dirt ingress. The button can be pressed and is a separate part, showing that Delta Armory wants us to have the realistic looks we deserve!

The magazine release is on the right side of the magazine well and is ideally positioned to be pressed with the trigger finger from a firing grip for right-handed users. Left-handed users can use their support hand thumb to press the release, and this can be done quite fast with a little practice. The surface of the mag release is textured to provide the necessary gripping qualities, and is protected from accidental presses by the "magwell fence", a raised protrusion in the receiver which stops the mag release from catching on your gear as you move.

The adjustable HOP-up unit is located inside the mock ejection port over on the right side of the upper receiver. This device allows you to adjust the amount of backspin applied to your BBs and tune the DA-C04-EGL for your ammo weight of choice, looking for the flattest possible trajectory. The Rotary HOP-up adjuster can be accessed by holding the charging handle back, after which the dust cover will spring open and the mock bolt plate will retract. The rotary HOP-up design is known as the latest and greatest for M4 AEGs, and it is always nice to see up-to-date internal parts, even in reasonably priced platforms like this.

The pistol grip of the DA-C06-EGL boasts a refined grip angle for greater comfort when shooting with the stock fully collapsed and in more modern shooting stances. Each flank of the pistol grip includes fine crackle texturing, with additional linear texture on the front and back straps for perfect wet weather handling.  The trigger guard is build into the receiver to improve strength and is enlarged to allow for gloved users. The trigger itself 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 no matter what you choose to mount to the plethora of 20mm rails on the DA-C04-EGL, the sling plate will be strong enough to support the weight.

To the rear of the sling plate, we come to the M4/AR-15 buffer tube, which is constructed from the same strong high density polymer used for the receiver. The buffer tube offers 6 positions of stock adjustment for the pre-installed Delta Armory battery stock, allowing you to set the stock at the perfect length to suit your body type and loadout. 

The stock itself is a slimline design unique to the latest releases from Delta Armory. Featuring a QD sling socket on either side, a low-profile adjustment lever on the bottom together with conventional "footman loops", aka sling slots, the highlight of this stock is its rubber butt plate featuring lattice checkering and an angled section at the toe for providing grip in the most modern shooting stances, with or without body armour. If you have a preferred stock design, the stock can be swapped for alternative M4/AR-15 AEG stocks if you want to change up the looks!

The buffer tube also serves as the battery compartment for the DA-C04-EGL. To access the battery compartment, you will need to pull the stock adjustment lever (located on the bottom of the stock) out and hold it in place, after which you can slide the stock off the buffer tube, revealing a Deans/T-Plug battery connector inside. We recommend a 7.4V 1450mAh LiPo in stick configuration for the DA-C04-EGL though you may need to keep the stock extended to fit this battery inside. Delta Armory recommends a LiPo battery measuring 1.4 x 1.9 x 10 cm approximately for full functionality of the sliding stock. 

On the inside, we are treated to some decent pre-upgraded parts, even in this CHARLIE™ line platform. The gearbox shell is reinforced to cope with stronger springs and the spring guide is a quick change example making power tuning a breeze. Inside the version 2 gearbox, we have an SHS piston with a full rack of steel teeth and an SHS tappet plate to guarantee reliable feeding. The gearset is constructed from steel with an 18:1 ratio, and the gears themselves run on 7mm bushings for a smoother, unlaboured gearbox report. 

The new EAGLE ETU/MOSFET system takes centre stage, offering more programmable options than ever before, including 3 or 5-round burst mode, binary trigger, sniper delay, AUG mode, semi-auto only and precocking. The ability to program this wide variety of modes using the trigger and selector of the gun itself gives the DA-C04-EGL the edge over practically any other platform in this price range. To provide the accuracy needed to deal with long-range foes, the DA-C04-EGL is equipped with a 6.03mm tightbore inner barrel offering higher FPS with the same spring and improved accuracy potential. 

If you love an affordable AEG platform packed with advanced features, you'll love the new EAGLE ETU-equipped AEGs from Delta Armory. This, the DA-C04-EGL 10" KeyMod M4/AR-15 AEG is a fantastic multi-role platform, great for long range with its 14.5-inch barrel but light and short enough to handle in a CQB scenario. If you like value-packed AEGs with fantastic build quality able to handle both indoor and outdoor skirmishes, the DA-C04-EGL is a great option!
