Bolt locked up on me...

[Mr.Untouchable]

... yesterday, I took my Imagine to my first day of play in a long time. Naturally, I was using Co2, but after about 3 hours of play, and in the middle of game, my bolt seemed to be uncocked, but when I tried to pull on it, it was stuck, and I couldnt get it to cock back. As soon as I got off the field, I tried a full Co2 tank, but it didn't do a thing. I then pulled the hopper off, and checked for any broken paint, but there was none. I then striped the gun open, but again, the bolt and striker would not come out. I finally gave up and took a screw driver to lodge the bolt out of the gun. It did come out with some force.

I then put the gun back together, and it seemed to be acting like it was out of Co2 (burping). So I tried adjusting the velocity and such, and it finally would cock at 350 fps

This problem is still not fixed, does anyone have any ideas why my bolt did what it did, and how I can avoid it. Or why my gun seems to be burping constantly.
