    Griffin Armament QD Blast Shield

    A cool new product from Griffin Armament the QD Blast Shield. 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. It goes over the Griffin line of QD 5.56 mounts including the Flash Comp, Muzzle Brake, Compensating Flash Hider, and Tactical Compensator.

    It is also compatible with A2 Compensators that fall within the NATO spec blueprinted dimensions. Although many companies manufacture A2 style compensators not all of them are dimensioned properly. Not Compatible with BCM, BCE or PWS muzzle devices.

    The Griffin QD Blast shield is available on our site Griffin Armament QD BLAST SHIELD - For Sale

    Cool concept. The video left out any accuracy issues. Does it help or hurt?
    I have a .243WSSM in an AR platform. I wanted to use a Levang linear compensator to direct the muzzle blast forward. I tried a dozen different loads and couldn't hit the side of a barn. Found out the Barrel manufacturer gave me a different twist than what I had requested, so I went to a heavier bullet, and still couldn't get accuracy.
    Removed the compensator and the accuracy came.

    What I didn't see in the video was an accuracy test with and without the QD Blast installed or not installed.

    I'm truly interested in this concept, but I'd need to see some accuracy comparisons.

    I've been looking at linear comps for my new AR pistol build. This looks like a great, quality product. I like the QD feature. It's too rich for my blood though. $150?! For what it is, I honestly expected a lower price point. There are dozens of linear comps, krink cans, etc out there that serve the same purpose for much cheaper. Sure they are not QD, but honestly, how long does it take to unscrew any muzzle device really? No offense to the manufacturer, of course, it's an inventive product. It's just not an option for me unless my salary drastically increases. lol. To each his own, I suppose.

    It won't change accuracy at all. It was designed not to effect the ballistics of the bullet.
