It's all rounded out, my dad is going to take it to work and use a machine to remove the screw, I'll need to find a place where I can find a replacement screw. Also, there will be another issue at hand once the screw is replaced. As I said the gun was shooting low, I was having a lot of problems with the pressure on the gun that night. When I highered the pressure to where it wasn't shooting really low, the HPR would leak. I got it to a point where there was a slight leak out of the HPR and the gun would shoot low but, still usable, however If I raised the pressure anymore there would be a huge leak out of the HPR.
