Compatibility - Choosing the Right Suppressor

Over-barrel suppressors have to fit over your rifle’s barrel and thread securely into place without touching the gas system on semi-auto rifles. This means that you have to take into account your barrel’s length and diameter as well as your gas system when choosing a suppressor.

If you are buying one suppressor for multiple rifles, you should choose one that fits over your thickest barrel and works with the barrel / gas system combination that has the shortest distance between the gas block and the muzzle. See the reference charts below, or call us at 800.858.0188 for help choosing the right suppressor for you.
