Real Avid Armorer's Master Wrench AR-15 Stainless Steel Multi-Tool

The Real Avid Armorer's Master Wrench is a professional-grade multi-function AR-15 armorer tool built around a heavy-duty stainless steel body with an ergonomic handle designed to apply serious torque for stubborn barrel and castle nuts.

Five specialized wrenches are combined in one compact 10.75" design: a Mil-Spec barrel nut wrench, a 10-post free-float barrel nut wrench, a castle nut wrench, a muzzle device wrench, and a receiver extension wrench for fixed stock tubes. An integrated 1/2" torque receiver lets you torque to spec when assembling an upper.

The ergonomic handle houses three interchangeable hammer heads - brass, nylon, and rubber - so you can drive pins and taps without marring finish or parts. From a complete field strip to a full barrel nut swap, the Armorer's Master Wrench is the go-to bench tool for assembling, disassembling, and maintaining AR-15 rifles and pistols.
