The Ruger 90484 Mini-14 20-round magazine in .300 Blackout is a factory-sourced feeding solution for shooters running this caliber through their Modern Sporting Rifles. Built with a steel body and heat-treated spring wire, this magazine is engineered for the same reliability you'd expect from Ruger's firearms—straightforward, dependable, and made to cycle reliably through extended shooting sessions at the range or in the field.
Whether you're stocking up for defensive training, precision rifle work, or just want backup magazines on hand, a 20-round capacity strikes a practical balance between firepower and handling. The all-steel construction means this magazine can handle the bumps and scuffs of regular use without losing its edge, and the heat-treated spring is built to resist the fatigue that rounds out cheaper alternatives.
Ruger's commitment to precise manufacturing translates to tight tolerances and consistent performance—no wobble, no feed issues, no surprises when you need the gun to work. If you're investing in a .300 Blackout platform, factory Ruger mags are the smart baseline choice for keeping your rifle running as intended.
