Feeding problem with non-hicap mags

[icaris]

Just got an A&K Masada and it seems to be having a bit of a feeding issue.

Works fine with the hi-cap it came with and the other hi-cap that came with my knight cqb, im guessing since you have to wind it, it helps push the bbs up into the hop up.

Tried my CA metal M4 mag, it works somewhat. When I pull the charging handle back I can see the bb's stopping half way into the hop up, turn the gun upside down and it fully drops in the hop up and fires fine. (it does do this with the hi-caps as well, but if you wind it more, it will push them up)

Should note to, its the shity plastic hop up, i'm looking for the metal one in Canada but not having any luck.
