Is it double feeding as in you get 2 shots with one pull or one "blank" shot then 2 bb's coming out? I had my gun (M4) do the double feeding thing and the culprit was in fact the BB's I was using. Otherwise it seems to be functioning perfectly and I would really just leave it be unless you really want that M4.
