Breek Arms BRK4331 Echo Single-Port Muzzle Brake | .30 Cal

The Breek Arms Echo Single-Port muzzle brake is a compact, steel accessory designed to work with the Breek-LOK 3QD quick-detach suppressor attachment system. It features a clean profile and multiple exhaust features to manage muzzle movement on .30 caliber platforms. The Echo can be pinned and welded to a 14.5″ barrel to meet the 16″ federal minimum overall length while remaining compatible with Breek-LOK 3QD mounts.

Use cases include competition and precision shooting where quick follow-up shots are required, and short-barreled rifle (SBR) or pistol-caliber carbine builds where a low-profile muzzle device and suppressor compatibility are desired.
