The Ruger American 223/5.56/.204/300 BLK 5-round polymer magazine is a factory original magazine designed for Ruger American rifles. Built from durable polymer, this magazine feeds the most common intermediate cartridges used in AR-platform and modern sporting rifle builds, making it a reliable spare or replacement for hunters, range shooters, and tactical rifle owners who need dependable ammunition storage and feeding.

Ruger's polymer magazine construction keeps weight minimal while maintaining the rigidity needed for consistent feeding. The 5-round capacity suits hunters in states with magazine restrictions and shooters who prefer controlled-rate-of-fire practice. Whether you're building out spares for your Ruger American or need a backup magazine for hunting season, this factory Ruger magazine is engineered to spec for your rifle.

The blue finish provides basic corrosion resistance and makes the magazine easy to spot in a range bag or truck. Like all Ruger magazines, it's straightforward to load, unload, and maintain—no learning curve, just reliable function when you need it.
