Description

The Griffin 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 versions have a cylindrical machined extension added to the mount. The 13.5mm 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 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″.

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

NOTE: The “45” designated options are only compatible with B&T spec “45 3-Lug” mounting systems.
