Who This Is For
This magazine is purpose-built for California-based AR-15 owners, competitive shooters, and range enthusiasts who need a state-legal magazine that meets the highest standards of reliability and build quality. If you're tired of polymer magazines that warp, crack, or fail to feed under pressure, the DURAMAG aluminum body offers a permanent, compliant upgrade that performs like a full-capacity mag in every way that matters.

Frequently Asked Questions
Is the 10-round block on this magazine truly permanent?
Yes. DURAMAG uses a proprietary internal block secured with a rivet to permanently limit capacity to 10 rounds. This method is designed to be non-removable, making the magazine compliant with California's fixed-capacity magazine laws without relying on adhesives or easily reversible modifications.
Will this magazine work with my AR-15 chambered in .300 Blackout?
Yes. DURAMAG's 5.56/.223 aluminum magazines are also compatible with .300 BLK, since that cartridge uses the same case head diameter and feeds reliably from standard AR-15 magazines. Always verify compatibility with your specific upper and feeding setup before extended use.
Why choose an aluminum magazine over a polymer one for long-term storage?
Aluminum magazines maintain their structural integrity under sustained spring pressure, meaning they won't bulge, warp, or crack during extended loaded storage the way some polymer magazines can. The hard anodized interior also reduces friction for smoother feeding, even after months of being stored at full capacity.
