NC Star AR-15 Crows Foot Lower Pro Tool Features The NcSTAR Crows Foot Lower Pro Tool is built from steel with a matte Black finish giving it the durability needed for repeated use in a workshop or armorer s kit. It combines AR15 and M4 castle nut spanner wrenches sized for telescoping stock tube assemblies eliminating the need to carry multiple separate spanners. An integrated A2 buffer tube wrench allows the same tool to service fixed stock configurations as well as adjustable ones. This consolidation of functions into one tool saves space and reduces the chance of misplacing a specialized wrench mid-build. A flat blade screwdriver built into the tool handles A2 buttstock plate screws so builders do not need to swap tools mid-task when assembling a fixed stock. The tool is compatible with both half inch and three-eighths inch drive setups giving it flexibility across different torque wrench and ratchet systems already in a builder s kit. Its steel construction stands up to the torque required for properly seating castle nuts and buffer tubes without stripping or deforming. Whether used by a hobbyist builder or a working armorer the NcSTAR Crows Foot Lower Pro Tool is a practical shop addition available for sale at GrabAGun.
