Breek Arms 2BO Outside Threaded 2-Port Muzzle Brake for AR-15 and AR-10

Breek 2BO Muzzle Brake – AR-15 and AR-10

The Breek Arms 2BO Muzzle Brake is a simple way to tame the recoil of your AR rifle, whether you’re running good old 5.56 or a beefier, .30 caliber cartridge. This two-port brake reduces muzzle rise dramatically compared to an A2 flash hider, and includes a crush washer for ease of installation. If you’re looking to pin and weld, this brake also brings a 14.5″ barrel to a legal 16″ length.

This Breek muzzle brake also features outside threads, so you can attach the Breek Arms Castle Blast Shield. Muzzle brakes are effective, but very loud, especially in indoor spaces. The addition of the Castle Blast Shield will turn this muzzle brake into a linear compensator, throwing sound and concussion away from the shooter for a more comfortable shooting experience.

Includes 1 crush washer for easy timing and installation.  Does not include the Castle Blast Shield.
