Real Avid Master-Fit 30mm Barrel Nut Wrench

The Real Avid Master-Fit 30mm Barrel Nut Wrench is a stainless-steel armorer tool for 30 mm free-float barrel nuts. Its fixed 30 mm profile gives it a clearly defined fit rather than the compromise of an adjustable wrench. That dedicated size is the key specification to confirm before ordering.

A purpose-built barrel-nut wrench is useful when the workpiece needs full engagement at a known size. Stainless-steel construction gives the tool the rigidity expected for bench tightening and removal work. Because the wrench is sized specifically for a 30 mm free-float barrel nut, it should not be assumed to fit other nut dimensions.

This Master-Fit wrench is a good choice when your build uses the exact 30 mm barrel-nut size it was designed around. Owners working on several barrel-nut styles may want to combine it with a broader crowfoot set. See more gun cleaning and maintenance tools for additional armorer wrench options.
