F-1 Firearms Brake by Arlis Nutter, Verified Owner, August 8, 2017
Amazing brake, High quality, and VERY Loud! (In a good way) If loudness is an issue than do not get this brake. Definitely turns heads at the range with the noise that comes from this! As like all other F-1 Firearms products, very high quality!
