About this muzzle brake
SilencerCo Asr Muzzle Brake M18X1 .338CAL is a muzzle brake.
Match the thread pitch to your barrel (1/2x28 on most 5.56 and 9mm barrels, 5/8x24 on most .308 and 6.5mm) and the bore to your caliber. A device that is too small for the bullet is dangerous.
California note: a muzzle brake is not a listed feature, so it works on featureless and fixed-magazine rifles alike. More brakes are in our muzzle brake section; see the California Rifle Compliance Guide for how each build works.
Manufacturer details
