Breek Arms Plan B Echo Single-Port Muzzle Brake | BRK4431

The Breek Arms Plan B Echo is an ultra-compact single-port muzzle brake engineered for the Plan B mounting system. Constructed from steel with a nitride finish, it is designed to provide controlled blast-vectoring from a single horizontal port while remaining compact for suppressor compatibility. Its form factor suits rifles chambered in .30 caliber that use 5/8-24 threading.

Applications: precision/practical shooting for faster follow-up shots, and use in competition or range sessions where muzzle control and rapid target re-acquisition matter. The Echo is intended to be part of a modular muzzle system and to simplify swaps between muzzle devices and suppressors.
