458 Socom Mags

[Snapshot]

I'm debating putting together a 458 socom AR. They take standard AR mags but they only fit 10 rounds.

So here's the million dollar question. Can I buy post ban magazines (that would be 30 rounds if they were in a 223 AR) since they are only 10 rounders in the 458?

IANAL but my guess is NOT LEGALLY. Since they are designed as .223 mags and post-ban they would be illegal to possess.

If you want .458, don't forget to consider the Garand...
