Just installing your Area 419 Hellfire suppressor mount is only one of the multiple uses offered by the company's Hellfire Wrench. This unique tool is milled from 60-61T-6 bar stock for durability and has a 5/8-inch hex head that enables users to attach their adapter straight onto the muzzle. The tool also features a 1 1/8-inch internal hex that enables easy installation of suppressor mounts and an external hex with the same dimensions that works to loosen stuck mounts. As an added feature, the mount also includes a bottle opener. Mfg: Area 419
