Hey guys. Basically while experimenting with my mags today I came across an annoying problem. For some reason, my classic army ak midcap magazines won't feed .25s at a mere 20rps. It feeds .2s fine but will skip a BB every other trigger pull on auto with .25s. My CYMA hicap feeds fine regardless of rps or weight so finding it pretty annoying. So what I'm asking is, anyone know if there is something I can do to make them feed? I'm pretty good with GB internals but never really needed to open up a mag before.
