The Real Avid Master-Fit 1-1/8″ Free-Float Barrel Nut Wrench is a purpose-built crowfoot armorer’s tool for AR-platform free-float barrel nut installation and removal. It delivers precise fitment to common mil-spec assembly nuts and is designed to accept standard 1/2″ drives. The tool uses titanium-coated stainless steel construction to provide tight tolerances and improved no-slip control. Its free-float handle layout improves access during assembly tasks and avoids makeshift tool adaptations.
