AR-15 UPPER RECEIVER VISE BLOCK.

The "Claw" is the perfect armorer tool for holding all AR-15 & M-16 upper receivers. Made of a solid one piece high strength polymer, the Claw is extremely durable. Simply clamp the Claw into a bench vise, slide the upper onto the Claw, secure with the two holding pins and begin installing your barrel and components. This tool is a must have from the work of an Armorer, to an avid Sportsman installing an Optic or scope. Also for the installation barrels, barrel nuts, optics, scopes, back up iron sights, PVS-14, quad rails, and much more.
