How to Install a Threaded Muzzle Brake

Most large-caliber weapons emit a bright muzzle flash and a loud noise when fired. To reduce these effects, some owners install muzzle brakes on their weapons. A brake will also reduce recoil by capturing and converting much of the muzzle blast's energy and using it to negate the recoil effect. These brakes can be installed on pistols and long-range rifles. The most common brake, the pin-on muzzle brake, also happens to be the most inexpensive and easiest to install.

Instructions

      Determine whether your firearm is threaded by taking it to a gunsmith for inspection. Some larger-caliber rifles are already threaded, while others need to be machined on a lathe.

      Unload your weapon and put the firing mechanism into the open position. Hold your weapon between your knees with the barrel pointing up, but away from your face. Oil the threads to prevent galling. Align the brake's threading with the barrel.

      Slide the brake into the barrel by twisting it all the way in until it is secure, to prevent vibration inside the barrel.
