I recently bought a barely used DM4 on ebay. The guy has excellent feedback and has been very helpful but my gun still leaks. It only leaks out the back of the bolt, through the hole. When i turn the reg on more powerful the air shoots out, and when i turn the reg down no air gets to the gun. I checked and replaced about 3 O-Rings but the problem still constists. I have no idea what would be wrong and the only thing I can think of is replacing every O-Ring and hoping. The gun is oiled btw and i used 2 different nitro tanks.
Anyone have this problem or know what to do??? Any suggestions are greatly welcomed. I wana use the damn gun
