I'm working on removing a pinned FH from a standard 14.5" M4 barrel that I bought. Should this barrel have left or right handed threads? I have cut it down to where the pin is and need to try and loosen it to remove the pin. My problem is that I'm working out of town in an apartment and don't have a vice to hold everything in place at them moment. Guess I'm going to have to see if a local gunsmith can help me the rest of the way in removing it.
