Breek Arms Echo Single-Port Breek-LOK 3QD Features The Breek Arms Echo Single-Port uses horizontal blast vectoring ports set at 90 degrees to direct propellant gas sideways rather than back toward the shooter significantly cutting felt recoil and muzzle rise. Six small holes machined into the brake create a secondary jet effect that further stabilizes the muzzle during rapid strings of fire. This reduced blowback improves shooter comfort over an extended range session and matters even more in competitive or defensive scenarios where fast accurate follow up shots count. Built specifically to pair with the Breek-LOK 3QD quick detach suppressor system the Echo integrates cleanly with that mounting platform for shooters who want quick suppressor attachment without sacrificing brake performance. Machined from 4140 hardened and nitrided steel the Echo Single-Port is built to handle sustained firing without losing its finish or dimensional accuracy. At just 2.06 inches long and 2.1 ounces it adds minimal length or weight to the muzzle end of a rifle. Threaded to the common 1/2x28 pattern for .223 Rem and 5.56 NATO rifles it installs directly onto most AR-15 pattern barrels and a peel washer is included to help achieve proper clocking during installation. Shooters building a clean quick detach capable muzzle setup around the Breek-LOK 3QD system will find the Echo Single-Port a well matched effective brake.
