Suppose you're looking for an advanced, compact AEG with plenty of features for its relatively low price. In that case, the Delta Armory DA-B03-EGL BRAVO™ SilentOps CQB M4/AR-15 AEG is probably the finest option out there currently! This Delta Armory rifle boasts an aluminium micro suppressor, CNC aluminium quad-railed handguard, and Delta's unique receiver constructed from high-density polymer and the superb Delta Armory EAGLE™ battery stock.

Inside, the DA-B03 is very well equipped for the price, boasting a 6.03mm tightbore inner barrel, rotary HOP-up unit and a reinforced version 2 gearbox equipped with a quick change spring guide, 7mm ball bearing bushings and an SHS piston and tappet plate. All of the internals are Tokyo Marui version 2 gearbox spec and compatible with aftermarket upgrades, meaning you can push the performance up even further down the line if you feel the need.

The EAGLE™ MOSFET is the star of the show, offering a range of programmable firing modes such as 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-B03-EGL the edge over practically any other platform in this price range.

Description

If you need an affordable and reliable CQB platform, the DA-B03-EGL BRAVO™ SilentOps CQB M4/AR-15 AEG from Delta Armory is a fine choice. The "Silent Ops CQB" setup boasts an ultra-compact front end with an aluminium micro suppressor and quad rail handguard pre-installed, giving you space for accessories whilst still prioritising agility and close-quarters domination.

Delta Armory's BRAVO™ range is the middle-of-the-road option from Delta, combining the high-density polymer receiver and buffer tube of the CHARLIE™ line with a CNC aluminium handguard and alloy outer barrel. This gives the platform more realistic weight distribution and an extra hint of realism without compromising the platform's nimbleness.

Like the ALPHA™ and CHARLIE™ AEGs from Delta Armory, BRAVO™ AEGs have more than their fair share of pre-upgraded parts, including a 6.03mm tightbore inner barrel, rotary HOP-up unit, 7mm ball bearing bushings, a reinforced V2 gearbox shell and a quick change spring system, plus the preinstalled programmable EAGLE™ MOSFET. If you prefer a simple yet solid internal feature set with room for customisation down the line when you get your eye in, the DA-B03 should suit you well!

Starting at the front end we can find a pre-installed mini suppressor which covers the 210mm 6.03mm tightbore inner barrel, mounting to the 4-inch alloy outer barrel. This gives the DA-B03-EGL Silent Ops the look of an integrally suppressed AR with an extremely compact front end which makes it easy to take corners in CQB. The suppressor mounts to 14mm CCW male threading, due to the short inner barrel, a barrel extension will be required to mount a tracer unit.

Surrounding the suppressor we have a 4-inch aluminium 20mm Picatinny quad-railed handguard with 20mm rails at the 3, 6, 9 and 12 o'clock positions, ready for any 20mm accessories you choose to add to complete your mission. The upper rail runs back and meets the receiver rail seamlessly to allow for longer optical sights to be mounted, including red dot sight and magnifier combinations.

The receiver itself follows the familiar M4/AR-15 format but with a unique Delta Armory aesthetic and is constructed from high-density polymer to keep the platform light and manoeuvrable. The finish on the receiver is consistent and strong enough to resist scratches more effectively than most metal receivers, making the DA-B03-EGL ideal for any audacious skirmishers!

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 adjust with your thumb, but not so easy that it can be changed 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. Being equipped with the EAGLE™ MOSFET also means you can program the controls for burst mode, binary trigger and even sniper delay, semi-auto only and AUG mode. Some of these may not be the best choice for this platform, but who are we to stop you?! 

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, reprofiled to match modern "billet" style receivers with their dynamic angles. This control does nothing on an AEG but is included regardless on this DA-B03-EGL to keep the rifle faithful to real M4/AR-15 rifles.

The charging handle is located at the top rear of the receiver and serves to retract the mock bolt carrier and open the dust cover on the right side of the upper receiver, giving access to the rotary HOP-up unit inside. The HOP-up allows you to tune the flight path of your BBs and set the DA-B03-EGL up for different ammo weights, looking for the flattest trajectory possible. The use of the rotary adjuster style is a nice touch and futureproofs the DA-B03-EGL with the most modern HOP-up design for the M4/AR-15 platform, boasting an improved ability to hold its setting under the vibrations of firing and being adjustable in finer increments than the older "gear" adjuster design.

The pistol grip of the DA-B0-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 is a "flat" trigger with a short finger ledge and textured front, making it ideal for pumping out rapid semi-automatic shots. The trigger guard is built into the receiver, improving strength and allowing gloved fingers easier access to the trigger than the standard AR flat trigger guard.

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-A19-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 1300mAh LiPo Stick Battery for the DA-A19-EGL though you may need to keep the stock extended to fit this battery inside.

The internals of the BRAVO™ series boasts more than their fair share of pre-upgraded parts, including a reinforced gearbox shell with quick change spring functionality and 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 so you can get your HOP-up set perfectly for your chosen ammo weight.

Inside the version 2 gearbox, we are treated to 18:1 ratio steel gears running on 7mm ball bearing bushings, an SHS piston with a full rack of steel teeth and an SHS tappet plate for reliable feeding, even at high speed. The new EAGLE™ 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-B03-EGL the edge over practically any other platform in this price range. 

If a relatively low-price, advanced CQB platform is on your to-buy list, the Delta Armory DA-B03-EGL BRAVO™ SilentOps CQB M4/AR-15 AEG is a fantastic choice. The EAGLE™ MOSFET puts it a league above any other CQB platform in the same price range. With generously pre-upgraded internals and superb, high-quality materials used throughout the platform, this rifle has it all!
