This magazine is ideal for California-based AR-15 owners, competitive shooters, and range enthusiasts who demand a compliant magazine that doesn't sacrifice the fit, feel, or feed reliability of a full-quality aluminum mag.

Frequently Asked Questions
Is the 10-round block on this magazine truly permanent?
Yes. DURAMAG uses a proprietary block combined with a permanent rivet to limit capacity to 10 rounds. This method is designed to be non-removable and meets the requirements for permanently altered magazines in states like California that restrict standard-capacity magazines. It is not a removable insert or pin.
Will this magazine work with my .300 Blackout AR-15 build?
Yes — DURAMAG's 10/20 aluminum magazine is compatible with 5.56 NATO, .223 Remington, and .300 Blackout chambered AR-15 and M4 platform rifles. The feed geometry is optimized to handle all three cartridges reliably, making it a versatile choice if you run multiple uppers on the same lower.
Can I store this magazine loaded for long periods without damaging the spring?
Absolutely. One of the key advantages of DURAMAG's aluminum construction and quality spring design is that these magazines are engineered for safe extended storage while loaded. Unlike polymer magazines that can warp or lose tension over time, the aluminum body holds its shape, and the spring is rated to maintain reliable feeding even after prolonged compression.

Scratched up BAD
These all came very scratched up, likely from poor storage conditions and not from shipping. I’ve ordered these before elsewhere, none had such cosmetic damage. Pretty disappointing, these color mags do not particularly look good with any blemish.
