Hi all, I bought an aeg cyma mp5k as a backup for my srs from “just airsoft” and am having problems with the mags. The 68rd one it came with works fine but I need a higher capacity (ideally mid caps). The problem is that i bought a 560rd one (also a cyma brand) but it does not lock in place. Comparing the two there a couple of minor differences but the main bit seems that the mag is came with has wider feed lips. Is this a common problem for cyma mp5k users? Any help would be massively appreciated!
