Excellent brake April 6, 2018
Reviewer: Peter  
I bought this brake for a 14.5 inch barrel to pin it and make a legal rifle length barrel. The fit and finish are perfect and gives the rifle a really nice look. Shooting 5.56 with this brake results in basically zero muzzle rise and very rapid follow up shots. The only downside is my friends on the firing line with me don’t care for the sidewards pressure and blast it creates, but who cares what they think anyways. Overall I’m highly pleased with the brake, and will be getting a taper mount flash comp to mount my Recce 7 suppressor that is currently sitting in NFA jail. Griffin Armament makes quality products.
