So I recently got a new gbb and wanted to attach an RIS on it so I bought the madbull sws rail. When I tried to attach the new barrel nut it the threads were tight and wouldn't screw on all the way (ended up with a gap between receiver and RIS). so I tightened it as tight as possible but now it's stuck can't get it off. The barrel nut has a propietary wrench which I can't seem to find since sws website only sells to the US.
