This assembly is designed to drop into Griffin Revolution pistol silencers or the Griffin Optimus, and allow the silencer to interface with a 3-lug muzzle. This is the ultimate way to attach your suppressor to a large variety of host guns! Things to be aware of: There are two standard sized HK patterned 3-lug systems: 9mm and .40/10mm. The 9mm system has a smaller diameter and neither are cross compatible to the other system. Make sure you buy the correct size mount for your host firearm (if you don't know which one you need, give us a call!). The 9mm coupler will fit inside of the Revolution 45 for use on 9mm platfor.
