Ruger American Rifle Rotary Fit 223 Rem 5.56 204 Ruger 300 Blackout

The Ruger 90440 American Rifle rotary magazine delivers a compact, reliable five-round feeding solution for Ruger American Rifles chambered in .223 Remington, 5.56x45mm NATO, 204 Ruger and .300 Blackout, engineered by Ruger to fit flush with the stock and preserve the rifle's balance and handling. Constructed from durable black polymer, the rotary design provides smooth, controlled cartridge rotation and a consistent feed angle, while the low-friction follower and precisely molded internals reduce drag and help prevent double-feeds or nose dents on soft-point rounds. Its slim profile keeps optics clearance and sling mounting options unaffected, making it a practical choice for range sessions, varmint hunting and patrol-style applications where a compact, reliable magazine is preferred. The magazine's Ruger-specific fit and finish ensure easy insertion and positive lockup, and the lightweight polymer construction minimizes added weight without sacrificing toughness, so shooters can maintain natural pointability and quick follow-up shots in field or training environments.
