Breek Arms 2BO-S Single Port Muzzle Brake – Recoil Reduction for Precision Shooting

Designed from 4140 steel and treated with nitride for superior hardness and durability, this brake features a 90-degree port that effectively mitigates recoil forces, enhancing shooter comfort and allowing swift target acquisition.
