I had a crap a-5 that uncocked itself all the time and the shop couldnt figure out what was wrong with that. This is why I came to BT because maybe they were better built.
I agree with robertseakykr, the detent could be causing your problem. Knowing your setup would also help.
As for your a-5, it sounds like the cocking handle spring and the drive spring might have be mixed up.
