Thread pitch and bore diameter are the two things to confirm: the device has to match your barrel's threads and be bored for your caliber or larger.
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.
