Griffin Armament 3 Lug Adapter .45 Cal .578x28

Overview

Griffin Armament 3 Lug Adapter Features The Griffin Armament 3 Lug Adapter is constructed from stainless steel with a Melonite QPQ finish producing a hard and corrosion-resistant adapter body engineered for the sustained thermal and mechanical demands of suppressor use on .45 cal platforms. The .578x28 thread pattern interfaces with compatible suppressor bodies providing an HK-patterned 3-lug barrel interface on host firearms with .578x28 muzzle threading. Melonite QPQ surface treatment delivers exceptional surface hardness and dimensional stability across repeated suppressor attachment and removal cycles. The .45 cal caliber-specific bore ensures proper alignment and fitment on HK-patterned 3-lug .45 cal host barrels without requiring additional hardware or modification. The .578x28 thread pitch is commonly found on .45 ACP pistol and carbine platforms making this 3 Lug Adapter well suited to that host ecosystem. Griffin Armament manufactures the 3 Lug Adapter to the same precision tolerances applied across their suppressor accessory lineup.
