Real Avid Master-Fit Barrel Nut Wrench - Titanium/Stainless Steel - AR-Platform Free-Float Handle (AVMF118BNW)

Building or maintaining an AR platform rifle deserves tools that won't compromise your work. The Real Avid Master-Fit Barrel Nut Wrench is a crowfoot wrench engineered specifically for the demands of AR gunsmithing—designed to grip barrel nuts securely while protecting finished surfaces from the marring that comes with generic tools. Constructed from titanium-coated stainless steel, this wrench combines durability with precision, giving you the confidence to apply accurate torque to one of your rifle's most critical components.

If you've ever jury-rigged a standard wrench around a barrel nut or worried about slipping and gouging your receiver, you know the frustration. This tool eliminates that compromise. The precision-machined profile engages tightly with the nut, reducing the risk of rounding or slip-induced damage. Whether you're assembling a new upper, replacing a free-float tube, or servicing an existing rifle, having the right tool makes the job faster and safer—and gives you one less thing to worry about once you're on the range.

Real Avid built this wrench for shooters and builders who care about fit and finish. It works with all standard 1/2-inch drive torque wrenches, so you can apply proper torque specs with accuracy and repeatability. If precision matters to you—and it should when you're assembling or maintaining firearms—this is the wrench you'll reach for.
