HK G36C dry firing?

[DeadBrainChimps]

The other day I was out airsofting with some guys. During one of the matches it randomly started dry firing. Switched mags, but it still was dry firing. This was the first time using the mid caps that came with the gun so I changed to my high caps. It still continued to dry fire. I have used the high caps before and never had an issue. The next day I took the gun apart which included the mag well, motor and gear box (still assembled), and the barrel cover. I looked through the barrel to make sure nothing may have gotten stuck, but it was clear. I connected the battery to the motor and gear box and shot it and there was air coming out. I'm not sure if that indicates anything?

Anyone have any ideas what might be going on? Also sorry if the terms aren't correct, I'm new to airsoft and still learning.

Possibly a bad hop up.  Happened to my mp5, installed new hop up and presto no more problems.  Not saying this is the guaranteed solution to your problem, just a thought.

make sure the nozzle is moving back and forth with each cycle. if it is just staying still than you have one of two problems and one u can easy check. first push on the nozzle inward, dos it move in than push back out? if no: 1 tappet plat may be stuck 2 return spring broke or 3 other component inside the gear box broke and locked it back. if yes: 1 you may have a broken tappet plate 2 (highly unlikely but happened like an odd duck to me once) nozzle came off the tappet plate 3 (even more unlikely) your sector gear broke or the cam fro the tappet plate broke. no matter what it really is, if the gun cycles but the nozzle dose not move you will have to open the gearbox. expect to at the least buy a new tappet plat and that should not cost to much. maybe in the ball park of $10 + whatever a tech will charge to install it. (note i do tech work if you need it) if the nozzle dose move with each cycle than you have a feed issue somewhere. this may be just a new bucking clean out the mags or check the hopup for any damage.
