I haven't been involved in a while, but iv been lurking a bit here and there. It seems that the gladiator wasn't a very popular model iv never been able to find much info about it.hopfully someone has one and has sorted this out before. My gun is leaking from somewhere by the power wheel, I think. I had this problem once before and found, There is a bolt between the barrel and front air cylinder. When you tighten this bolt the leak stopped. This time when I snugged it up the power wheel got very tight and difficult to turn. So I'm guessing there is something more wrong than loose connections. Bad o rings I'm assuming, but looking at the parts drawing it looks a bit intimidating and I'm not so sure about working on an HPA system. Any insight would appreciated thanks guys.
