GRIFFIN ARMAMENT 3 LUG BARREL ADAPTERS – 9MM / 10MM / 40S&W / 45ACP

Griffin Armament’s 9MM 3-Lug adapters are HK pattern and will work with any 3 lug silencer on the market made to this standard. They will also work with Griffin 3 lug interface assemblies.

The 5/8×24 and 13.5x1mm LH 9MM versions have a cylindrical machined extension added to the mount. The 13.5mm SIG TAPER 9MM MPX version has flats for a wrench on that cylinder extension and has the O-ring interface typical of 13.5×1 LH mounts. The other 3 Lugs are the smaller version pictured.

The 5/8×24 adapter is meant to provide a 3 Lug mount to 30 caliber barrels but is also compatible to 9mm barrels where that thread is uncommonly used. Most 30 caliber barrels are threaded 5/8×24 thread pitch.

1/2×28 Thread Total Length: 1.4375″. Based off of industry standard .625″ barrel threads, added length should be ~.8125″.
5/8×24 Thread Total Length: 2.125″. Based off of industry standard .625″ barrel threads, added length should be ~1.5″.

*The .45 3 Lug adapters are only compatible with the Griffin .45 3 Lug Interface Assembly.

Made from 17-4ph stainless and Melonite QPQ treated.
