Breek Arms LOK 3QD Echo Single-Port Muzzle Brake Features The Breek Arms LOK 3QD Echo Single-Port Muzzle Brake is engineered around horizontal blast-vectoring ports that direct propellant gas to the sides rather than upward cutting muzzle rise and keeping the sights on target between shots. Six small jet holes supplement the main port creating an additional jet effect that further stabilizes the muzzle during rapid strings of fire. Less blowback toward the shooter means improved comfort behind the gun a real advantage in competitive stages or defensive encounters where follow-up speed matters. The 1/2x28 thread pitch and 9mm chambering make it a direct fit for common pistol-caliber platforms running that thread standard. Machined from 4140 hardened steel and nitrided for corrosion resistance and a hard wearing surface the Echo is built to handle sustained use without degrading its finish. It mounts with the Breek-LOK 3QD system a quick-detach suppressor interface designed for fast secure attachment without sacrificing a clean low-profile look on the muzzle end. A peel washer ships with the brake to help achieve proper timing during installation and Breek Arms specifies a 20 to 30 ft lb torque spec for a secure mount. Designed and manufactured in America this compact brake suits SBR and pistol-caliber carbine builds looking for recoil control without added bulk.
