I am trying to swap the barrel on my RPR. I have heated it with a torch, wacked on the armorers wrench with a mallet, and used a 3 ft cheater bar each direction to try to budge that damn barrel nut. Do I need a action wrench for this thing. I have the barrel in a vise and it is fucking tight around the barrel and when I use the cheater bar I just spin the barrel in the vise.
Any advice?
