KAK Industry Plan B Radial Brake 1/2x28 – .223/5.56 & 9mm

The KAK Industry Plan B Radial Brake is a single-chamber muzzle brake designed to reduce felt recoil and muzzle rise on AR-15 pattern rifles in .223/5.56 and 9mm pistol-caliber carbines. Its radial port design directs gas evenly around the shooter, minimizing side blast while maintaining effective recoil management for faster follow-up shots.

This brake features a 1/2x28 thread pitch and includes a crush washer for timing and installation. Constructed from steel with a durable black finish, it's compatible with standard AR-15 barrels threaded 1/2x28. No gunsmithing required—installs with a standard armorer's wrench or adjustable wrench.
