Description
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, B&T, 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.
Due to the wide range of possibilities on muzzle devices and similar interfacing components we always recommend that you verify fitment and alignment of all parts after final assembly. Regardless if you use our parts or those made by other companies, its always a good idea to triple check your setup before live fire.

Good construction quality – needs to be paired with the adapter to ensure proper torque. If you are going Tri-Lug I would recommend this adapter

Got this to try on my CZ3+ after trying to get multiple devices to attach to my Rugged 3-Lug adapter. I got theirs because I previously acquired their Obsidian suppressor. They said their lug was “HK spec”. However, every HK spec device I tried would not attach to their 3 lug, including a KVP Mach 3 Linear Comp and B&T HK 9mm Flash Hider. When I got this today, I removed the Rugged and installed HBI’s and everything attached perfectly, including the Rugged Suppressor. Great adapter!

Installed this on a Springfield Kuna. The fit and finish is top notch. Combined with a Dead Air Tri lug adapter DA444 and a Mojave 9. Perfection! Your products always exceed expectations.
Thank you HBI

Also bought this for my Springfield Kuna. Very nice machining and works great with my YHM R9.
