The .458 SOCOM round is a custom round designed to work with the AR-15 platform. What is great about this round, is that you can use it with your existing 5.56 30 round magazines, and it will hold 10 rounds. If you are in California, you can therefore be able to, legally have large capacity 5.56 magazines, as long as the rounds going in are .458 SOCOM. Ammunition prices are very high at around $2.50+ per round. We are a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for us to earn fees by linking to and affiliated sites.
