  • 6.03mm Tightbore inner barrel
  • CNC Aluminium handguard
  • Pre-upgraded version 2 gearbox 

If you love the looks of the DA-C05 Silent Ops but wish it was longer with more metal parts, the Delta Armory DA-B08 BRAVO™ 9" SilentOps M4/AR-15 AEG is just what you need! BRAVO™ AEGs are constructed with strong high-density polymer receivers and aluminium handguards, making them perfect for those who want to step a bit closer to realism while maintaining maximum energy and agility in game. 

The Silent Ops 9" is rocking a quad rail handguard styled after the KAC Freefloat RIS paired with a suppressor hidden beneath, giving it the stealthy styling of shorter suppressed ARs with enough length to hide a 400mm 6.03mm tightbore inner barrel inside for maximum long range effect. The tightbore is paired with a 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, resulting in a build focussed on reliability and strength with a slight accuracy advantage for good measure!

Whether you're looking for a DMR base gun or a long-barreled AR platform which won't weigh you down, the Delta Armory DA-B08 BRAVO™ 9" SilentOps M4/AR-15 AEG will suit your needs perfectly!

Full description

Description

If you like the sneaky AR look but want something a bit longer than the common integrally suppressed M4, the Delta Armory DA-B08 BRAVO™ 9" SilentOps M4/AR-15 AEG should be right up your street. As a Delta Armory BRAVO™ series AEG, the DA-B08 is equipped with a CNC aluminium handguard and suppressor but keeps the high density polymer receiver and buffer tube of the CHARLIE™ series to keep the build light and easy to move with. 

On the inside, Delta Armory's BRAVO™ range has 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. If you're seeking a long range platform with a stealthy aesthetic, the Delta Armory DA-B08 BRAVO™ 9" SilentOps M4/AR-15 AEG gives you far more bang for your buck than a platform this price deserves!

Starting at the front end we can find a pre-installed suppressor which covers the 400mm 6.03mm tightbore inner barrel, mounting to the 7-inch alloy outer barrel. This gives the Silent Ops 9" the look of an integrally suppressed AR but a slightly longer overall form, ideal for long range scenarios. The suppressor mounts to 14mm CCW male threading but due to the inner barrel length, a 7-inch barrel extension will be required to mount a tracer unit.

Surrounding the suppressor we have an 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. Unlike similar integrally suppressed platforms with KeyMod or M-LOK handguards, you will never have trouble mounting mission essentials to the quad rail of the DA-B08 as it doesn't require clearance between the handguard and suppressor. 

The receiver follows the familiar M4/AR-15 format 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-B08 Silent Ops 9" ideal for those who skirmish like a bull in a china shop!

The fire selector can be found on the left side, positioned just above the pistol grip for fast access from a firing grip. The selector provides 3 modes of fire; Safe, semi-auto and full auto, with a 90-degree throw between each mode. The modes are all indicated in classic M4/AR-15 style, with recessed markings in block capitals matching real MilSpec M4 receivers. The magazine release is on the right side of the magazine well and is easily reached from a firing grip with the trigger finger, allowing for super swift emergency reloads and the enviable handling the M4/AR-15 platform is known for.

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-B08 Silent Ops 9" to keep the rifle faithful to real M4/AR-15 rifles.

The charging handle is located at the top rear of the receiver and doesn't need to be pulled before the first shot. It instead serves to retract the mock bolt carrier and open the dust cover on the right side of the upper receiver, giving us 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-B08 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 Silent Ops 8 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-B08 Silent Ops 9" 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 guard is the standard M4/AR-15 flat style, and 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 no matter what you choose to mount to the plethora of 20mm rails on the Silent Ops 9", 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 and also serves as the battery compartment for the DA-B08. 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-B08, 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.

The internals of the BRAVO™ series boast 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 internals are all Tokyo Marui spec, meaning aftermarket upgrades are prolific for those who want to maximise performance. 

If you're in search of a platform for long-range work but don't want the excessive weight that comes with a full metal build, you'll love the DA-B08 BRAVO™ 9" SilentOps M4/AR-15 AEG from Delta Armory. With reinforced internals focussed on reliability and a great mix of polymer and aluminium parts, the DA-B08 is a fantastic choice for the skirmish focussed Airsofter with a long-range leaning!
