Just a quick little video I (well, my girlfriend technically) shot, not sure if mags jamming in the magwell upon reload is an issue for a lot of people, but it sure was an issue for me. Here's a quick fix I came up with.

There are spacers out there for LCT AKs that fix this exact issue, but because the CYMA already has "half" of a spacer there, you will have to remove your standard spacer to then use an LCT spacer, as well as having to pay money for it in the first place. This circumvents that, plus you can make it yourself out of anything you want and it's free, provided your "hands don't grow out your butthole" (as we Russians say).
