I’ve been investigating big bore rounds for the AR platform. One of the things I have learned is that the 458 SOCOM uses standard mags/followers but at much reduced capacity. A 20 round 223 magazine only holds 7 rounds of 458.
That made me think about AR owners who live in states with 10 round magazine limits. If they buy a 458 upper for their AR then they should be able to buy as many 7 (20) round magazines as they like, correct? If they own a 223 upper then it would make sense to buy a couple of smaller mags that can’t hold more than 10, but it seems that unless you get caught loading 223 into your 458 mags you could buy as many as you want. If I were in a ban state I might consider buying a 458 upper even if I really didn’t want one.
