Breek Arms Plan B Echo Single-Port Muzzle Brake 9mm 1/2x28 Steel - Black Nitride

The Breek Arms Plan B Echo is a compact single-port muzzle brake designed for 9mm AR-platform pistols and pistol-caliber carbines. Machined from 4140 hardened steel with a black nitride finish, it threads on at 1/2x28 TPI and installs in minutes with a standard 13/16" wrench. A peel washer is included for proper timing; torque to 20-30 ft lbs at install.

At just 1.75" overall length, the Echo sits low enough to clear most handguards and suppressor-mount interfaces, while the single-port design redirects muzzle gas to help control recoil on rapid follow-up shots.

Part of Breek Arms' modular Plan B system, the Echo brake is compatible with the company's Breek-LOK 3QD quick-detach hubs and suppressor mounts, letting shooters step up to a suppressor-ready rig without swapping the brake. Designed and manufactured in the USA.
