Double muzzle brake for Ruger Mini-14 rifles. Easy to install and reduces muzzle rise and recoil from both slots and holes. Slips on around your original front sight post and tightens in place. Requires no gunsmithing and retains your original front sight post, matte finish steel and not made by Ruger. Will not fit heavy barrels, target barrels, or International stocked versions. Does not fit guns with serial numbers above 195+ range because the barrel is too large. Legal to own. NOT a flash suppressor.
