Real Avid Master-Fit 13-Piece AR-15 Crowfoot Wrench Set - Precision Gunsmithing Tools for AR-15 Maintenance
- Handle Description:
- Heavy Duty Torque Wrench
Building or maintaining an AR-15 demands the right tools—and the Real Avid Master-Fit 13-Piece AR-15 Crowfoot Wrench Set delivers the precision gunsmithing capability that separates a solid build from a professional one. This comprehensive kit pairs 12 specialized crowfoot wrenches with a heavy-duty torque wrench, giving you everything needed to work with barrel nuts, muzzle devices, and castle nuts without guesswork or marring your components.
Crowfoot wrenches are the gunsmith's secret weapon for reaching tight spaces and applying exact torque where conventional wrenches can't fit. Real Avid's Master-Fit design means each wrench is tailored to fit specific AR-15 fasteners snugly—no wobble, no slop, no damage to your build. The titanium-coated stainless steel construction handles repeated use and resists corrosion, while the included torque wrench adjusts from 10 to 150 foot-pounds with ±4% accuracy, so you can dial in the exact spec called for by your barrel manufacturer or preferred build guide.
The torque wrench features a ratcheting head with 45 teeth for fine incremental adjustments and optimal leverage in cramped receiver spaces. Its dual-directional function handles both standard and reverse-threaded components—critical if you're working with modern muzzle brakes or flash hiders. Everything ships in a hard-sided case with structured foam, keeping your tools organized and protected whether you're a weekend tinkerer or a full-time armorer.
