Thank you guys!
There is about a half centimetre of play and when I push up on the mag it fires 100% like when upside down. Not sure why I didn't try that before, I guess seeing the BBs in the mags and having just had the mechbox open had me worried.

Is there any known solution to a problem like this? Why wouldn't the mag be sitting correctly with the hop-up?

Thanks for the quick replies everyone!
