Wheeler Engineering 1100182 Delta One-Piece Aluminum Gunsmithing Action Rod

The tool eliminates stress on the receiver when installing a barrel and works on all .223 Remington, 5.56mm, & .300 Blackout caliber barrels with standard barrel extensions. The rod also works on both forged and milled upper receivers, and the design enables you to work on the upper with no need to remove your sights or optics. A simple twist and lock design makes it easy to hold the tool in place when working, and a gas port index rod is included in the design.
