Matrix S&T Spectre Airsoft AEG Sub Machine Gun (Package: Gun Only)

"The gun is a nice size and weight. Shoots alright. It died after I shot about 250bbs. Just suddenly stopped working. I can here the trigger click but nothing else. The stock doesn't stay locked down. Kept hitting myself in the head which was annoying. Magazines are expensive, hard to find, and low capacity. I checked the insides and it doesn't appear to have a fuse.
