The QD Blast Shield was designed to offer significant concussion reduction for the end user and other team members operating in the immediate vicinity. Often team members in CQB environments experience concussion from muzzle blast that is not only deafeningly loud, but also can cause prolonged headaches that can last for days afterwards.

Especially effective on short barrels, the unique design of the QD Blast Shield directs concussive force forward allowing an end user to rapidly reconfigure muzzle device function. Ultra strong 17-4PH stainless steel and Tig welded construction provides a robust material and build method to withstand intense use and full auto fire without fear of failure. The body is fluted in the same way as our QD suppressors, increasing strength to weight ratio for added geometrical strength, while increasing surface area for faster cooling.

Melonite QPQ surface treatment provides an extremely hard, durable, and attractive finish.

The QD mechanism is fast, positive, and free of wear prone geometry commonly found in ratcheting devices. The QD Blast Shield also comes with a shim set and overtravel stop to refit your A2 compensator for optimal use.

The Griffin QD Blast Shield is compatible with our line of Gate-LOK mounts in 7.62 and 5.56mm, including the Gate-LOK Flash Comp (5.56mm)Gate-LOK™ Hammer Comp (5.56mm), Gate-LOK™ Stealth Flash Hider (5.56), and Gate-LOK™ Flash Comp .30cal (7.62mm). Discontinued products the QD Blast Shield is compatible with: M4SD Muzzle Brake, Linear Comp, Compensating Flash Hider, & Tactical Compensator. *Not compatible with 30SD Flash Suppressor and 30SD Muzzle Brake*

It is also compatible with A2 Compensators that fall within the USGI A2 spec blueprinted dimensions. Silencer interface was designed to fit the USGI A2 government contract compliant muzzle devices. We cannot guarantee fitment with an A2 style compensator due to the broad tolerance range of both import and domestic devices from various brands. For guaranteed fitment, we recommend the purchase of a Griffin mount.

Although many companies manufacture A2 style compensators not all of them are dimensioned properly. Not Compatible with BCM, BCE or PWS muzzle devices.

Griffin Armament has continued to pursue product development that will enhance hearing safety in tactical and shooting sport situations. The QD Blast Shield is a great product for those that would like to reduce the concussion of their muzzle devices.

Compatible up with projectiles up to 9mm.

    QD Blast Shield (Gen 2)

    Published by Charlie Winn on 4th Sep 2021

    Great product!!! I own the Gen 1 when it came out. I love the design of both the Gen 1 & Gen 2. Great accessory for my 10.5" uppers. Only a couple of range sessions so far and it's been good.

    You might need a new A2

    Published by BryanB on 23rd Aug 2020

    Turns out a lot of manufacturers are making slightly out of spec A2 flash hiders. It's not very surprising, these things retail for around 7 bucks. I have a few on hand to test and found that both my BCM and PSA A2's were just oversized enough to prevent the blast shield from locking on. My CMMG A2 works fine. YMMV, we're talking about variances measured in thousandths of inches here.

    I also have a BCM Mod0 comp that is advertised as being compatible with A2 accessories and it does indeed work.

    G.A. Gen2 blast shield

    Published by Cj on 13th Sep 2019

    I purchased the Griffin armament gen 2 blast shield and it locks up to my b.c.m. mod 0 comp. Very nicely. I have no muzzle flash at all with the blast shield. Thank you Griffin armament.

    Blast shield

    Published by Derick Broyles on 17th Jul 2019

    To it to the range and it works great! Only a 4 star because only shot about 50 rounds and when you take the blast shield off the finish on the flash suppressor already had carbon residue on it.

    Griffin Armament Blast Shield Gen 2

    Published by J Stog on 23rd Jun 2019

    The Blast Shield Gen 2 Looks and Performs fantastic.
    In the description they say it’s not compatible with BCM Muzzle Devices but I will tell you it fits/ works excellent in my BCM MOD 0 Brake. These Blast Shields beat the hell out of the finish on the muzzle devices though but that’s with other brands as well.
