Frequently Asked Questions
Is the 10-round block permanent, and can it be removed?
Yes — DURAMAG uses a proprietary block and rivet system specifically designed for permanence and compliance. The block is not intended to be removed and is constructed to meet the requirements of capacity-restricted states like California. Attempting to remove or modify the block would violate state law and void any applicable warranty.
Will this magazine work with all AR-15 and M4 pattern rifles?
This DURAMAG is designed to fit standard AR-15 and M4 platform rifles with STANAG-compatible magazine wells. It feeds reliably with 5.56 NATO, .223 Remington, and .300 Blackout ammunition. As with any magazine, it's always a good idea to confirm fit with your specific lower receiver before extended use, especially with aftermarket or non-milspec builds.
Why choose an aluminum magazine over a polymer option?
Aluminum magazines like DURAMAG offer superior resistance to flex and swelling under heat and repeated loading cycles. Unlike polymer, aluminum maintains its geometry over time, which contributes to more consistent feeding and longer service life. DURAMAG's hard-anodized coating also reduces friction for smoother round stripping and easier loading, making it a preferred choice for shooters who demand consistent, long-term performance.

Excellent product & service !
I love metal mags and to have some pinned 20's is icing on the cake ! Had to purchase a gray because I needed 5 and they only had 4 ODG in stock. Quick delivery and secure packing. Would buy again.
