NEW!! Griffin Armament QD Blast Shield Muzzle Device

Posted on October 13th, 2014 by ar15news

If you’ve ever stood next to someone shooting an AR you’ve definitely felt and heard the ear drum shattering concussion with every shot. The new QD Blast Shield from Griffin Armament helps reduce this concussive force by redirecting it forward away from the shooter or those next to the shooter. The QD Blast Shield is certainly not the first of its kind but has some unique features that make it one of the best designs I’ve seen.

One of the main features I really like about the QD Blast Shield is that it will work with multiple muzzle devices that Griffin Armament offers but is also compatible with the readily available A2 flash hider giving you multiple different options for the muzzle device you use under the QD Blast Shield. However, I would recommend one of the Griffin Armament QD 5.56 mounts if you really want to have a sweet setup!

The QD system itself is another thing I feel Griffin Armament improved on. Instead of a screw on or ratcheting system the QD Blast Shield locks on by pressing the locking gate to the side and engaging the spring clip. To remove the QD Blast Shield you have to manually disengage the spring clip and then pull the locking gate out to the side making it virtually impossible to disengage accidentally. This is the same QD system that they use on their flagship M4SD Silencers.

There are plenty of nice features of the QD Blast Shield but the last one I’m going to touch on is the visually appealing aspect of it. This thing just looks awesome. The black Melonite finish and triangular shape is much different than other similar products on the market but these looks are an upgrade in function as well which you can read more about below.

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 while triangular gas flow pockets allow the muzzle device to retain it’s specific performance goals. Ultra strong 17-4PH stainless steel provides a robust material to withstand intense use and full auto fire without fear of failure. Fluted geometry in the triangular shield lightens the unit while providing internal front supports for the muzzle device.

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 QD 5.56mm 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.

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.
