one of the first tests I do is turn the rifle upside down and hand feed the BBs into the hopup with no mag. This will tell you if it will at least fire. Doing this eliminates the possibility of the mag not being perfectly placed by either not being high enough, forward/backward enough, too high, springs not pushing BBS etc.
Also turn the hopup all the way down for your testing and eliminate the possibility that it's set too high and actually blocking the BB from leaving.
when it fails to fire, is the sound any different from when it was working? Or does it just sound like a regular dry fire?
