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

The Real Avid Master-Fit Barrel Nut Wrench is a purpose-built gunsmithing tool designed for installing and removing barrel nuts on AR-platform rifles equipped with free-float handguard systems. Machined to the exact 1-5/16" geometry demanded by modern free-float barrel nut designs, this wrench delivers a precise, dedicated fit that protects both the tool and the firearm during torque application.

Constructed from a combination of titanium and stainless steel, the Master-Fit is built to withstand repeated use in the shop without corroding, galling, or deforming under load. The free-float handle design keeps the body of the wrench clear of the handguard, preventing contact marks, scratches, or finish damage while you drive the barrel nut to spec. Its slim profile allows it to slip inside the channel of most free-float handguards for clean, unobstructed access to the nut.

Whether you are swapping a barrel, upgrading to a new free-float rail, or performing routine build work, the Real Avid Master-Fit provides the dedicated fit and confidence that a generic crescent or adjustable wrench simply cannot match. Designed specifically for the AR-15 / AR-platform ecosystem, it is a must-have addition to any AR builder's tool kit.
