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.

Great option for 3 lug with 300BLK January 14, 2016
Reviewer: Michael McManus from Boykins, VA United States  
I purchased two of these because my favorite mount is the H&K 3 lug system and the thought of not having to change the mount and using it with my cans with 300BLK subs appealed to me. The shipping was very fast and the quality was excellent. I installed them on both of my 300BLK uppers, one 8.5" barrel and one 7.5". The only problem I had was on the 8.5" barreled upper is about 33% to 50% of the time, depending on the ammo (Remington 220 and American Eagle 220) the rounds would go supersonic. They were obviously loaded just subsonic and the higher pressure of the little bit longer barrel in combination with the way the mount makes the blast chamber just a little smaller was enough to push the bullet supersonic. (free bore effect)  None of that is a flaw of the adapter nor Griffin's fault. It didn't happen with the direct thread mount or with the 7.5" barrel. I am going to just put a minimalist taper mount on my 8.5" barrel so I can run supers with it too with my 30 cal can.
