Breek Arms PLAN B Echo S-Port Muzzle Brake 5.56 – 1/2x28 Thread

The Breek Arms PLAN B Echo S-Port muzzle brake delivers effective recoil management for 5.56 NATO rifles through a strategically designed port pattern that directs gas rearward and outward. This brake reduces felt recoil and muzzle rise, allowing faster follow-up shots and improved control during rapid strings of fire. The S-Port configuration balances performance with shooter comfort, making it suitable for competitive shooting and tactical applications.

Constructed from heat-treated steel with a durable black finish, the Echo S-Port features a 1/2x28 thread pitch for compatibility with standard AR-15 barrels and similar platforms. Installation requires a crush washer or shim kit for proper timing and is straightforward with an armorer's wrench. The brake's compact profile does not add excessive length to the barrel and maintains a clean sight picture. Compatible with 5.56 NATO and .223 Remington chamberings.
