These 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 5/8x24 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 13.5x1 LH mounts. The other 3 Lugs are the smaller version pictured.


The 5/8x24 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 5/8x24 thread pitch.

1/2x28 Thread Total Length: 1.4375". Based off of industry standard .625" barrel threads, added length should be ~.8125".
5/8x24 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.

    Griffin armament 3 lug adapter

    Published by Jacob Pedigo on 13th Sep 2021

    High quality and great fit on my Aero AR 9. Can transition my silencerco hybrid 46 from my mp5 3 lug adapter with no issue. Highly recommend if you in the market for an adapter.

    MPX must have

    Top quality machining, perfect fit on an MPX. The precision craftsmanship is evident by the tight tolerances of the whole Griffin 3-lug system.

    Works Great with Gemtech GM9 Too

    Published by JimK_TX on 12th Oct 2020

    Bought these to use with my 9mm devices and my Bushwhacker 46, but low and behold they also work with my Gemtech GM9. Bought the Gemtech quick detach adapter MP5 style. Works great.

    Well made. Sometimes I have problems putting on and removing the suppressor. Maybe it will be easier after it gets broke in. I hope.
