There's just probably an issue with the selector switch. If it fires in auto, it would fire in semi. And the fact that you CAN get it to fire in semi means its not the battery.
that is what I tought...I just emptied a mag (almost 80rounds) and it only did it once...switched to auto for some burst and then came back to single...everything was alright so I don't understand what is the problem...
(also...damn I love this gun ! nice buy I just did :smile: )
