I purchased a 3 lug barrel adapter. However, the adapter would not work for the mount I was using. I contacted customer service and within hours contacted me and allowed me to return the product.
The hands down best customer service I have ever had.
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.
The hands down best customer service I have ever had.
A good fit, patiently waiting for 1/2-28
Fits on my 9MM AR perfectly. Mates up to my Optimus 9 and makes for quick and easy installation and removal. This and the 3 Lug Interface for a suppressor are a necessity.
Fitment on my MPXK was great! My Rugged Obsidian suppressor with 3 lug adapter goes on and off with ease. Wish they would put some kind of channels In the adapter to resemble the original bird cage.
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
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!
Awesome product! Great quality workmanship and I would recommend this 3 Lug Adapter if you have a Sig MPX.
Solid fit, and easy to install. Makes switching from firearm to firearm quick and easy.
Simple and solid attachment. Fits snug with three lug interface. Very easy connect/disconnect
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.
