HK 3 Lug Adapter




HK type 3 Lug adapter ideal for pistol caliber suppressor mounting. They are perfect for use with calibers 9mm and smaller (9×19, .300blk, .380acp, etc…). Machined to HK specs this adapter mates with the 3 lug mounts made by all of the major US manufacturers of suppressors (including: Silencer Co, Liberty, Gemtech, AAC, DeadAir, Rugged and more). These adapters are machined from chromoly steel and finished in black nitride. Please select your barrel thread type from the drop down box above.

NOTE: Our 3lug adapters are designed to interface with industry standard “15mm” nominal HK type mounts. Some of the newer Griffin Armament 3lug components deviate slightly from this and may not mate with our adapters. The 3lug mounts manufactured by all other known companies are compatible and fit perfect.
