Griffin Armament 3-Lug Coupler Kit 9mm

The Griffin Armament 3-Lug Coupler Kit 9mm is an integral 3-lug interface assembly designed to add minimal length to the suppressor while allowing QD mounting on many Griffin suppressors. The 9mm kit fits H&K standard 9mm 3-lug adapters, Griffin 3-lug adapters, and compatible barrels from RCM, Michael’s Machines, and German HK brand barrels.

This coupler kit is built with 17-4 stainless steel and a 17-7 wire spring for heavy-duty performance in full-auto applications. The adapter requires minimal deflection of the spring bushing during installation in some cases, which can help avoid the need to modify hand stops or grips that sit close to the 3-lug adapter.

Griffin guarantees fitment with Griffin 9mm 3-lug barrel adapters, while some other 9mm barrels and barrel adapters may also be compatible.
