The Real Avid Master-Fit 5-Piece A2 Crowfoot Wrench Set is a purpose-built gunsmithing tool collection for serious AR-15 builders and gunsmiths working on A2-style platforms. If you're assembling, upgrading, or maintaining an A2 upper or need precise control over barrel nuts, castle nuts, muzzle devices, and buttstock components, this set puts the right tool in your hand for every job. Real Avid engineered these crowfoot wrenches from titanium-coated stainless steel to deliver tight tolerances and no-slip fitment—critical when you're working with the small, recessed fasteners that define AR assembly.

The set includes four specialized crowfoot wrenches sized for the most common A2 assembly tasks: dual options for castle nuts (extended and standard), a free-float barrel nut wrench (20-hole and 4-hole compatible), a 3/4-inch muzzle device wrench, and a 5/8-inch muzzle device/A2 buttstock extension tube wrench. Paired with these is a heavy-duty 1/2-inch drive torque wrench calibrated from 10 to 150 foot-pounds, accurate to ±4%. With 45 ratcheting teeth clicking every 8 degrees, you get precise leverage positioning and the freedom to work from multiple angles. The dual-directional feature even handles reverse threads, so you can confidently torque fasteners that work against traditional rotation.

Organization matters in the shop. The set comes with a hard-sided storage case and a rail holder system that keeps each wrench indexed and protected. No fumbling through a toolbox or stripping a wrench in dim light—everything stays organized and within arm's reach. Whether you're a professional gunsmith, a dedicated builder, or someone who maintains their own rifle collection, this set eliminates guesswork and delivers the precision that separates a quality build from a problem down the line.
