*HK 3 Lug Information*
The 3 lug barrel profile was originally designed by H&K in 1964 for use on the MP5 SMG to mount blank firing adapters, flash suppressors and grenade launchers. Suppressor mounts were later developed and patented by Mr. Timothy D. Bixler of South Central Research Corp in 1988. Later developments include producing adapters for standard threaded barrels to allow usage of 3 lug compatible suppressors and muzzle devices on other firearms, including the ubiquitous AR-15.
HK 3 lug adapters are now the defacto standard for quick detach capability for pistols and pistol caliber carbines. Until now the only way to torque a HK 3 lug adapter was by use of a standard 17mm open end wrench. This method could result in marring of the adapter and had limitations with respect to short barrels and long hand guard systems.
