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.
