Designed for calibres up to 45/70. These brakes are an easy, convenient screw on design that do not require any crush washers or special tools. Just screw the muzzle brake on all the way to the shoulder of your barrel, then fasten tight with the tool provided. Due to the perfectly aligned machined gas ports, this design disperses energy evently around the brake, creating greater balance, thus eliminating deviation from the muzzle blast.
