Drop-In Muzzle Brake - No Thread Cutting Or Welding Required
Easy-to-install muzzle brake simply replaces the factory bushing on any full-size Colt 1911 Government model or clone. Some of the combustion gas is redirected through helical ports cut at the same angle as the 1-16" rifling found in most 1911 barrels to and help control muzzle rise and reduce felt recoil. Reduces muzzle flash, too. Machined from hardened 4140 steel to resist blast erosion.
