Real Avid Master-Fit 1 5/16" Barrel Nut Wrench - Titanium/Stainless Steel for AR-Platform Free-Float Handle

Building or maintaining an AR platform demands precision tools that won't trash your components. The Real Avid Master-Fit 1 5/16" Barrel Nut Wrench is purpose-built for the critical task of installing and torquing free-float barrel nuts—the kind of specialized tool that separates a clean, professional build from one marred by improvised solutions. Machined from titanium-coated stainless steel, this wrench fits standard 1/2-inch drive torque wrenches, letting you apply accurate torque to one of the most important fasteners on your rifle.

Too many builders grab whatever crowfoot wrench is handy and risk rounding the nut or marring the finish. The Master-Fit's precision-machined geometry grips the barrel nut decisively, minimizing slippage and component damage during installation. Whether you're assembling an AR-15 with a free-float handguard or working on a precision rifle build, you get the engagement and clearance geometry you need without improvisation or risk.

Real Avid designed this wrench specifically for gunsmithing work—no adaptation required, no worrying about whether a standard tool will fit the application. The titanium-stainless construction resists corrosion and delivers the durability a shooter's toolbox demands. If you take your builds seriously, this wrench belongs in your kit.
