I had an older prianna that i bought of ebay recently. The first time i used it, it worked fun and shot great. Then i tried to play with it and the rear cocking bolt wouldn't stay cocked. I tried a new tank and compressed air. It still did the same thing. I was thinking that it need a new bottom line but i didn't hear a leak at all. I then took it apart and all the O-rings were fine and all the pieces were together. I don't know what the problem is any ideas???
