The Real Avid AVMFESCNW Master-Fit Castle Nut Wrench eliminates stripped castle nuts and rounded edges with precision-machined titanium and stainless steel construction. This dual-purpose tool handles both extended and standard castle nuts on AR-platform rifles with professional-grade accuracy.
What Makes This Different
The Master-Fit design features precisely machined engagement surfaces that distribute torque evenly across castle nut teeth, preventing the damage common with standard wrenches. The titanium construction provides exceptional strength while remaining lightweight, and the tool's geometry ensures proper alignment every time. Unlike generic castle nut tools that can slip or round edges, this wrench maintains consistent contact throughout the entire rotation.Key Features
