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.
