Read Detailed Description

The MASTER-FIT® Armorer’s Crowfoot Wrench series is engineered for the builder who demands shop-level precision and a mar-free finish. When it comes to AR15 assembly, generic, sloppy-fitting wrenches can round off edges or slip under pressure. Each Master-Fit wrench is precision-machined to provide a high-tolerance, no-slip interface with your specific hardware, whether you are clocking a muzzle device, staking a castle nut, or seating a stubborn free-float barrel nut.

Professional Performance
Every wrench in this lineup is designed to fit a 1/2-inch drive torque wrench, allowing you to meet exact manufacturer specifications for safety and reliability. Built from high-quality materials, these tools are designed to withstand high-torque demands without flexing or deforming, significantly reducing the risk of "tool walk" or finish damage on your receiver and handguard.

Comprehensive Compatibility
The Master-Fit system allows you to select the exact tool required for your specific build. From standard Delta Rings and A2 extension tubes to oversized free-float barrel nuts and specialized 3-prong flash hiders, these individual heads provide a centered load distribution that standard multi-tools cannot match.
