I installed a kart xact fit barrel a while back on a project gun. I was looking at it today and I think I could’ve fit it better. It was my first time, that particular barrel. Would it be ok to have a mechanic friend of mine tig weld (the one that uses electrial current? Not sure if that’s right) the sides of the hood and the raised spots that were in the first upper lug, the spot kart has you fit, and attempt to fit it better? Any precautions or advice?
