Real Avid Master-Fit Free Float Barrel Nut Wrench - Titanium/Stainless Steel for AR-Platform

The Real Avid Master-Fit Free Float Barrel Nut Wrench is a precision AR-platform gunsmithing tool designed to install and remove free-float barrel nuts on AR-pattern rifles. Built by Real Avid, the Master-Fit wrench is purpose-made for the unique geometry of free-float handguard barrel nuts, delivering confident engagement and torque without marring the nut or the receiver threads.

Constructed from titanium and stainless steel, the wrench offers long-term corrosion resistance and the rigidity needed to break factory-tightened nuts loose. Its profile is sized to clear most free-float handguards while still providing the leverage and contact surface a gunsmith or home builder needs during an upper assembly build, barrel swap, or handguard upgrade.

Whether you are assembling a new AR-15 upper, servicing an existing free-float handguard, or running a full custom build, the Real Avid Master-Fit Free Float Barrel Nut Wrench is a focused, purpose-built addition to any AR build tool kit.
