Description

The Real Avid Master-Fit Castle Nut Wrench is a gunsmith tool built for assembling AR-15 platform rifles. It is designed to fit MIL-SPEC AR-platform castle nuts, including both extended and standard versions, so builders do not need to rig up generic wrenches for these jobs.

The wrench is made from stainless steel with a titanium coated finish and a silver color. The raw text describes tight tolerances for solid nut-gripping strength and enhanced no-slip control, and it notes a 1/2" drive crowfoot style.

The tool is intended for torquing the most common MIL-SPEC assembly nuts on AR-platform builds, where precise fitment matters.
