Breek Arms PLAN B Echo S-Port Muzzle Brake 9mm – 1/2x28 Thread

The Breek Arms PLAN B Echo S-Port muzzle brake reduces felt recoil and muzzle rise on 9mm pistol caliber carbines and pistols, improving follow-up shot speed and control. The S-Port design vents gases through strategically placed side ports to counteract muzzle climb while maintaining a compact overall length suitable for PCC builds.

Machined from heat-treated steel with a durable black finish, this brake threads onto standard 1/2x28 barrels and requires no timing or crush washer—install hand-tight and stake per manufacturer instructions. The PLAN B mounting system allows quick attachment of compatible accessories when needed. Compatible with AR-9 platforms, pistol caliber carbines, and any 9mm firearm with 1/2x28 threaded barrel.
