The AAC Blackout 51T Muzzle Brake is an excellent muzzle device for reducing recoil, as well as reducing wear on suppressor internals when used as a suppressor host for short barreled rifles.

Made of hardened 17-4 Steel, the AAC 51T Muzzle Brake muzzle device redirects propellant gasses and unburned powders laterally, reducing recoil. This device features a 51 tooth ratchet mounting system that is compatible with many AAC sound suppressors, such as the newest revisions of the M4-2000, 762 SD and new 762-SDN-6.

When used with a suppressor mounted, the muzzle brakes acts as a sacrificial blast baffle, absorbing the abrasive effects of unburned gun powder and high speed, high temperature gasses.
