Use this tool to install or remove an HK style 3-Lug adapter on any barrel. Each double sided tool is compatible with both 9mm (small bore) and 45ACP (large bore) type 3-Lug adapters. Tool is designed to be coupled with a 1″ wrench or used with a socket extension to install a 3-Lug adapter “blind” under a handguard or barrel shroud, where the location of the 3-Lug adapter does not allow the use of a wrench or direct driver. An example would be the installation of a 3-Lug adapter onto a pistol length barrel under a carbine or rifle length handguard. This tool is machined from steel and zinc plated for a maintenance and corrosion free life.
