Wheeler Delta Series Crowfoot Wrench – AR-15/AR-10 Castle Nut Tool

The Wheeler Delta Series Crowfoot Wrench is a dedicated armorer's tool designed specifically for installing and removing AR-15 and AR-10 castle nuts. This professional-grade wrench fits standard receiver extension castle nuts and provides the leverage needed for proper installation torque without marring the finish. Essential for building or maintaining modern sporting rifles, it eliminates the need for improvised tools that can damage parts.

Constructed from heat-treated steel with a durable finish, this crowfoot wrench features precision-cut teeth that engage the castle nut securely. The 1/2-inch drive design allows use with standard torque wrenches for proper spec installation (typically 35-40 ft-lbs). The tool's low-profile design provides clearance for most stock configurations and allows visual confirmation of staking after installation.
