Griffin Armament 3-Lug Adapter

This is a precision-engineered 3-lug adapter designed to interface your 1/2x28 threaded barrel with any standard HK-pattern 3-lug suppressor on the market. Griffin Armament built this adapter to work seamlessly with their own 3-lug interface assemblies as well as quality suppressors from other manufacturers that follow the same proven standard.
