Of course i know what the brake is for but reading sss description it clearly says noise on he varmint calibers. Coppied and pasted bellw.

We manufacture and install our own muzzle brakes. They are symmetrical designed with 30 radial holes and 6 linear holes for sound control. On most varmint calibers the reduction is approximately 60%. Most people can't tell where the barrel ends and the brake begins. Price includes installation.
