Okay here is my situation. I was taking the outer barrel-hop up assembly out of my gun. I found a wire that was stripped for about a quarter of an inch. Pieces of the copper were ripped apart but not all of it. My semi auto does not work well or even at all most of the time. My last match my full auto started to stop working for a little but then it got better. My question is how can if fix the wiring without replacing it. I don't want to replace it because I am new to teching.
