Install A Muzzle Break

The end of a military issue iachine gun features a muzzle break.

Installing a muzzle break on a rifle has noticeable advantages. The primary purpose of a muzzle break is to reduce the volume of noise a rifle makes when fired. However, this purpose may not be the biggest advantage of installing a muzzle break. In addition to deadening the noise a rifle makes, a muzzle break also reduces the recoil – or kick – of a rifle by almost 50 percent. For young or small people, this means they can fire a high-powered rifle without having to submit to the standard punch of a rifle with a great deal of power.


1. Purchase the muzzle break you feel is appropriate for your rifle. Take your rifle to the gunsmith and pay to have the muzzle threaded with male threads that match the female threads of your muzzle break.

2. Retrieve your rifle, now threaded, from the gunsmith.

3. Wrap the rifle’s fore-stock in the towel tightly. Place the towel covered portion of the rifle in the vice and tighten it snugly. Do no over tighten the vice or you risk damaging the fore-stock.

4. Press the butt of the muzzle break – the end with the threads – against the threads of the muzzle. Twist the muzzle break gently clockwise. If the muzzle begins to feed into the muzzle break, continue. If the muzzle break begins to twist and rotate at an angle not parallel the the rifle’s muzzle, back the muzzle break off by twisting counterclockwise and begin again. If you force the muzzle threads into the muzzle break threads during this critical first step, you will strip the threads on the muzzle or the break.

5. Continue to twist the muzzle break clockwise onto the muzzle if it is twisting on straight. Once the muzzle break butts up against the last of the muzzle’s threads, give the muzzle break a twist with extra torque to secure it on the muzzle. You have successfully installed your muzzle break.
