Okay here is my problem. I am sure this is on here somewhere but I can't find it lol. Whenever I really get my MR2 going fast, some times it comes un-cocked, and it always comes un-cocked in full auto, and burst. Why does it do that?
Thanks alot guys.

It sounds like when the bolt is cycling fast, the marker isn't getting enough air. You would probably want to switch out the valve spring for one that will allow it to stay open longer, which, I believe would be a lighter spring.

Yeah it is definately the Anti-chop bolt working. Any time it prevents a chop, the bolt will uncock. Glad to know it is working! You are probably outshooting your hopper. Even thought the rated speed of your hopper might be above 13 bps, it may not be able to sustain that rate without missing a few balls here and there.
