Have regular mags with no visual and doesn't give a ammo count except a magazine count. Have points to be used for certain weapons to get certain types of mags to see how many rounds you have*. *=Generally PMAGS with a Rough estimate. Not all weapons being able to have said magazines only the main 30 RND AK/STANAG variants.
It's a suggestion, also only being able to see the current magazine would be nice as well. Like having to take it out of the gun and inspect it by holding R. But the rest of the magazines just show up as a number without letting you know how many rounds you have in that next mag you might reload.
