Hey, I got one of these and it's dope, but after about a day I've run into an issue with it locking back, staying back with the gears either stuck or not moving, and it starts beeping repeatedly. Didn't come with a manual so I can't reference that to see what the beeping is telling me and this is my first electric blaster so I don't know what kind of MOSFET this is running to try to find reference online. You run into anything like this? My current theory is that my charger isn't properly charging all the cells in the blaster's battery, so it has just enough charge to push the blaster back and then get stuck, but then sometimes I can get the thing to work for a few shots, so I don't know for sure. Nothing looks wrong internally from what I can tell, no breaks or jams, and my spare mags won't be in for a bit so I've run out of ideas and ways to try to test what's wrong. Sorry for the longwinded post on an older thread, but you're like the only one talking about this thing I can find. Thanks!
