Breek Arms BRK4331 Echo Single Port Muzzle Brake Black Nitride Steel 5/8"x24 Threads 30 Cal Compatible w/ Breek-LOK 3QD

The Breek Arms Echo single-port muzzle brake is a compact recoil-management device built for shooters running 30-caliber rifles with the Breek-LOK 3QD quick-detach suppressor interface. If you're building a short-barrel rifle, working a competitive platform, or simply want to tame muzzle rise and felt recoil, the Echo delivers straightforward performance in a clean profile that won't bulk up your build.

At the core, the Echo uses 90-degree horizontal blast-vectoring ports to redirect gas and reduce both recoil impulse and muzzle rise. A set of six additional small holes further breaks up the blast, helping you stay on target during rapid follow-up shots. All this means less head movement, faster sight picture recovery, and noticeably less blowback in your face—a real comfort gain during extended shooting or defensive training. The brake is threaded 5/8"x24, standard for 30-caliber barrels, and engineered to work seamlessly with Breek-LOK 3QD mounts if you plan to add a suppressor later.

Breek Arms manufactures the Echo from 4140 hardened steel with a black nitride finish, delivering durability without unnecessary weight. At just 1.7 ounces and 2.06 inches long, it maintains a compact footprint—especially handy if you're pinning and welding to bring a short barrel up to federal length or building out an SBR-format upper. A peel washer is included for installation. This is a purpose-built tool for shooters who refuse to compromise on recoil control or suppressor compatibility, all made right here in the US.
