This two-sided wrench is just what you need to tighten or loosen the barrel nut on your AR-15 rifle. Works on both Mil-Spec and free-float barrel nuts. Made from the same high-quality steel as our AmmoBot frames. Just attach a standard 1/2" drive socket wrench or torque wrench.
This wrench will not fit specialty barrel nuts from Aero Precision or other non-mil-spec barrel nuts.
