Having issues feeding from AI AICS mags

[MerkZ]

Hey, my build is having issues feeding and I'm wondering if any of you have any ideas. My build is as follows:

Terminus Zeus SA QA version
KRG whiskey-3
Accuracy International AICS mags

The funny thing is, my 5 round mag feeds flawlessly, but both my 10 rounders have a weird hangup. I took a video showing my problem, hopefully it's clear enough.

I've thought about attempting some modifications to the feed lips but I don't want to mess up the mags haha.

Again, any ideas would be massively appreciated! Thanks!!

Measure your mags lips at several points with calipers and then you can always return it to those dimensions if you mess it up too bad and start over

Best, straightforward way to tune your magazines.
