Looks like the AR mags are 30 and the AK mags 28.
Too bad they don’t make mags for AK platform Saigas. They’re a little harder to come by.
28 or 30, the point is, you ought to have at least 10 or 15 mags for each battle rifle. When it looks like the SHTF, load ALL the mags you own.

I keep several around loaded to half capacity, and rotate those monthly to combat spring fatigue.
