I have a m4 airsoft gun and I thought my problem was the fuse. But they keep popping. Isit my motor?

it very well could be your motor or any other part of your gun it might be the popping mechanism that allows it to pop can you call the makers of the gun and run the situation past them to see if its a easy fix or if its not how you you go about getting new parts or a replacement something isn't working right
