Description

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.

    They work as advertised.

    It works as advertised. Machining and finish are very nice. The price is seriously inflated and Griffin knows that. It's too bad with the money you spend on this stuff they can't make all the extras a little more reasonable

    Quality Piece

    Everything GA makes is quality. I used one of these to convert a direct thread setup to 3 lug and I wish I had done it sooner. Highly recommended!

    3-lug adapter

    Published by Kyle on 1st Apr 2019

    Griffin has done it again. They take amazing products and make them better. The fit and finish is top notch. This makes switching cans from pcc's to fixed barrel pistols effortless. I can switch from my 9mm AR, to Ruger pcc, to 15-22, to a 22 pistol in no time. More time shooting and less time fooling with cans. Buy one for each host you wont regret it.

    Published by Ryan on 14th Sep 2018

    The 1/2x36 3-lug adapter is machined with excellent quality and finish. It is not just limited to this adapter, I own about 15 various Griffin products and all of them are very high-end. Really pleased time and again. They will be a continued go-to source for many of my needs.
