The REAL AVID Master-Fit® AR-15 Crowfoot Wrench Set is a professional-grade AR-15 armorer's tool kit engineered to deliver the precision, durability, and versatility needed for firearm assembly, maintenance, and customization. Featuring 12 specialized crowfoot wrenches and a precision Master-Fit Torque Wrench, this comprehensive system is purpose-built to service a wide range of AR-15 components, including barrel nuts, flash hiders, and castle nuts. Whether you're a professional gunsmith, armorer, or dedicated firearm enthusiast, this set provides the confidence needed to apply torque accurately while protecting valuable firearm components.

Constructed from titanium-coated stainless steel, each crowfoot wrench is designed to resist corrosion, wear, and deformation under heavy use. The specialized "Deep Seat" fitment provides maximum surface contact with firearm components, minimizing slippage and reducing the risk of marring finishes or damaging critical parts. Paired with the included torque wrench adjustable from 10 to 150 ft-lbs, users can confidently tighten components to manufacturer specifications with ±4% accuracy.

Designed with both performance and organization in mind, the set comes housed in a durable hard-sided storage case featuring dedicated foam cutouts and a molded torque wrench cradle. This keeps every tool protected, organized, and ready for use whether in the workshop, armory, or at the range.
