The CMMG 9mm ZEROED Muzzle Brake is an excellent option for any 9mm rifle or pistol. This 2-inch long muzzle brake has quite an aggressive design, with two angled ports on the beach side which do an excellent job of recoil mitigation. Moreover, it has a couple of smaller ports on the top, designed to decrease muzzle rise and help you stay on target. The CMMG 9mm ZEROED Muzzle Brake has no ports on the bottom, so you can shoot it from a prone position or a table without worrying about dust signatures.

Made from 4140 Steel, this muzzle brake is quite durable and comes with a black nitride finish. It uses a 1/2"-28 TPI thread pitch and is very easy to install on your rifle. You also get a crush washer with this muzzle device, which you can use to time it properly.
