Griffin Armament 3 Lug HK Barrel Adapter - 5/8x24 Listing ID: 2932314

Selling one Griffin Armament adapter for 3 lug/tri-lug muzzle devices for barrels with 5/8 x 24 thread patterns. Less than 300 rounds through it in total; fits HK spec’d 3 lug barrels perfectly (was used with a Rugged Obsidian Suppressor 3 lug adapter with no issues). Very minor wear from normal use that has zero effects on function, finish is in great condition. Threads and lug edges are sharp and the lockup with a suppressor or compensator is excellent

MANUFACTURER INFORMATION BELOW:

These 3 Lug adapters are Heckler & Koch (HK) pattern and will work with any 3 lug silencer on the market made to HK standard. They will also work with Griffin 3 lug interface assemblies

This 5/8x24 has a cylindrical machined extension added to the mount. It also features flats for a wrench on that cylinder extension for easy install/removal.

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.

5/8x24 Thread - Total Length: 2.125". Based off of industry standard .625" barrel threads, total added length to barrel should be ~1.5" (without suppressor or other muzzle device attached)

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