MadBull Barrel Nut Wrench
- Works on the standard type of barrel nut but some specific kinds of rail systems require a special barrel nut as the standard one will not allow the front system to fit.
- This wrench is for the Madbull Daniel Defense series, RIS II series (M4A1 and MK18) and Omega X series front set barrel buts.
- This wrench is a single piece of steel with a dull back coat finish, just like a neat little tool grade item should be.
