G&G tr4-18 not feeding properly

This one is pretty weird.

So when I load midcaps (tried various types, as well as hi caps) all the way, halfway, 3/4, etc, the gun seems to not feed properly, and the BBs will shoot maybe 1 or 2, then nothing for 5-10 trigger pulls, then BBs roll out the barrel or sort of explode out all at once, then the gun shoots a few normally, and back and forth more or less.

IF i take these same mags and only load in 30 rounds, they feed and cycle properly with essentially zero issues.

I have changed the hopup unit entirely, and tried different bucking. This apparently does not seem to be the problem.

This model of gun has a blowback mock bolt piece that i am reluctant to take off, but it looks like I'll need to. Does anyone have any ideas on what the problem could be?
