I just picked up a used ICS MP5SD5. I tested it out with the high cap it came with, and it was fine. I then tried the extra mid cap mags that came with it, and every time I try using them, they either double feed, or don't feed at all.
I'm using .25g BB's, fully charged battery. Idk what brand these mags are, but the guy said he got them here:

All 3 mags don't feed properly. is there anything I can do to actually make them work?
thanks.
