Griffin Armament
The Griffin Armament Gen 2 QD Blast Shield is a muzzle device accessory built for shooters who need to manage concussive force in tight quarters or high-volume fire. Whether you're running drills indoors, operating in close-quarter battle scenarios, or just tired of the punishing blast that leaves your shooting buddies with day-long headaches, this QD blast shield attaches to your existing A2 compensator to redirect concussive energy forward and away from you and those around you. It's one of the most effective ways to reduce felt concussion on short-barrel rifles while keeping your rifle's ergonomics and controls unchanged.
Built from 17-4PH stainless steel and TIG welded for durability, the Gen 2 QD Blast Shield is engineered to handle full-auto fire and hard use without compromise. The fluted body design mirrors Griffin's suppressor construction—it adds geometric strength, reduces weight, and increases surface area for faster cooling between strings of fire. The Melonite QPQ finish delivers a hard, corrosion-resistant coating that looks sharp and stands up to the elements. The quick-detach mechanism is fast and positive, with no ratcheting wear points, so you can swap between the blast shield and a suppressor whenever your mission demands it.
Fitment is straightforward with A2 compensators that meet USGI spec tolerances—the package includes a shim set and overtravel stop washer so you can dial in your compensator for optimal performance. The QD Blast Shield is also compatible with Griffin's line of SDQD silencer mounts in both 5.56 and 7.62 calibers, including the Flash Comp, Muzzle Brake, Linear Comp, Compensating Flash Hider, and Tactical Compensator. Note that A2-style compensators vary widely in manufacturing tolerance; Griffin recommends purchasing a Griffin-branded mount for guaranteed fitment, though the shield will work with spec-compliant government-contract A2 devices.
This is a serious tool for professionals and competitors who understand that concussion management isn't just comfort—it's part of operational readiness and team safety. If your shooting setup includes an A2 compensator and you're looking to reduce blast without adding a full suppressor to your lineup, the Gen 2 QD Blast Shield delivers real results.

The QD Blast Shield is designed to fit A2 compensators that meet USGI specification tolerances. Because A2-style compensators vary widely in manufacturing tolerance across different domestic and import brands—including BCM, BCE, and PWS—fitment is not guaranteed with non-Griffin muzzle devices.
