Ruger SR-556 10-Round Magazine - Black
The Ruger SR-556 10-Round Magazine is a factory OEM replacement mag chambered for .223 Remington and 5.56x45mm NATO. Built from blued steel with a corrosion-resistant black finish, it runs a heat-treated steel spring, high-visibility orange polymer follower, and an integrated over-travel stop for reliable seating and feeding. The 10-round capacity makes it a smart pick for capacity-restricted states, bench rest shooting, and varmint hunting where a shorter mag clears the bipod. Compatible with the Ruger SR-556, AR-556, and standard AR-15 platform rifles.

Perfect For My Range SessionsBeen running this mag in my SR-556 for a few months now and it just works every single time, no drama. I use it mostly for bench rest shooting at the range since my state has the 10 round limit and this thing fits and seats perfectly every time I slap it in. The steel body feels really solid compared to some of the polymer mags I've tried before, and I love the orange follower so I can tell at a glance when I'm empty. Only thing I'd say is it took a couple of loads to get the spring broke in but after that it feeds SMOOTH. Honestly couldn't ask for more from a factory mag.
Solid steel construction feels super durable
Spring feels a little stiff right out of the box
