Griffin Armamant QD Blast Shield FULL Review

Griffen Armament sells this blast shield under the false claim that it will fit on NATO SPEC A2 muzzle devices & their own muzzle devices. They also mention that it will NOT work with A2 "style" devices as they're not built to NATO spec. in the Attached video, you will easily see how i prove that they will NOT FIT NATO SPEC A2 "BIRD CAGE". their customer service sucks, their engineering dept is obviously inept, and most of all they are deliberately LYING to their customers hoping that you will Waste an additional $100 to purchase their comp but that defeats the porpoise of having a INTERCHANGEABLE DEVICE.
