What's the spec for the width of the magazine feed lips on 30 round aluminum mags?

And for you guys that always seem to have answers to the endless questions about specs for this and that what is your reference source? And where can I find it? Lol.

ETA: Wanted to add that I primarily have Okay and Colt mags with a handful of Center Industries thrown in the mix, as well.

Width of the gap or the mag lips themselves?

Roger.

Once upon a time Brownells carried the feed lip gauges....#NSN 5120-01-574-0036.

I haven't seen them in a long minute.

I tried looking for the gage, and, yup, looks like it’s no longer available.
