it pretty much sounds like the same problem I had when I recieved mine, I'll put a magazine into it and it will fire, but it wouldnt rotate the magazine... Lucky I ordered acouple spare mags when I bought mine and was able to narrow it down to that pretty fast. Hopefully thats the problem cause umerax will mail you a free mag. But call canadian airgun source, if they wouldnt do anything about it, then think about buying stuff from DL airgun in the future, they are in west canada, but they are amazing to deal with, they are the only people ill buy from, I learned that the hard way
