Description
The Griffin Armament 3-Lug Adapter is a precision barrel accessory that lets shooters mount any HK-pattern 3-lug suppressor to a 9mm Luger host barrel threaded 1/2″-28. The adapter features an HK-pattern 3-lug interface, making it compatible with any 3-lug silencer on the market built to this standard, including Griffin Armament’s own mounts.
Machined from high-strength 17-4 PH stainless steel and finished in a rugged Black Melonite QPQ coating, this adapter delivers excellent wear and corrosion resistance. At only 1.43″ long, it adds minimal length to the host firearm while providing a secure, repeatable 3-lug mounting interface for fast suppressor attachment and removal.
Whether you run a pistol-caliber carbine, PCC, or 9mm pistol with a 1/2″-28 threaded barrel, the Griffin Armament 3-Lug Adapter offers a durable, tight-tolerance mounting solution for your HK-pattern 3-lug suppressor.
