Frequently Asked Questions
Is the 10-round block permanent, and can it be reversed?
Yes — DURAMAG uses a proprietary block-and-rivet system that permanently limits this magazine to 10 rounds. This is not a removable limiter or a pin that can be pulled out; the block is designed to be irreversible, making it fully compliant with California's magazine capacity laws for new purchases.
Will this magazine work reliably with .300 Blackout as well as 5.56 NATO?
Yes. The DURAMAG SS™ is engineered to feed .223 Rem, 5.56 NATO, and .300 Blackout reliably from the same magazine body. The advanced internal geometry and anti-tilt follower accommodate the different cartridge profiles without requiring any modifications to the magazine or your AR-15 platform.
Is it safe to store this magazine fully loaded for extended periods?
Absolutely. One of the key advantages of 410 stainless steel construction is that it will not flex, warp, or take a set like polymer magazines can over time. The spring and follower are designed to maintain consistent tension during long-term storage, so you can keep this magazine loaded and ready without worrying about feeding issues or spring fatigue.

Perfect for service rifle matches
Solidly built and reliable. Perfect for people who live in. states with stupid magazine capacity restrictions. Great customer service and fast shipping from Goodland Guns. Will probably order a few more.

Duramag ar-15 10/20 Mag.
Got it a day or so ago, right when it was suppose to come. So far have looked it over and it looks great. Have locked it into my rifle and have not run any ammo through it yet. Good product for my crazy state (NY) and great service from Goodland Guns.
