double feed

[blair]

HI just changed the stock ics hop up bucking for a systema bucking i put it all back together and the hop seems to work fully on = bb take off not on = drop, so appears to be working,

however when i put a new magazine in it will always fire 2 bbs on the first shot then after that its fine

what could be the problem?
