Ruger Ar-556 300 Aac Blackout Fits Sr-556 Takedown Steel Finish

The Ruger 90526 AR-556 30rd 300 Blackout magazine is a rugged, made-in-USA replacement designed to fit Ruger AR-556 and SR-556 takedown rifles, delivering dependable feeding for .300 AAC Blackout (7.62x35mm) rifles during range sessions and field use. Constructed from black steel with a robust finish, this 30-round capacity magazine provides a solid, snag-resistant profile that mates precisely with AR-556 receivers and takedown configurations, making magazine swaps and transport straightforward. The internal spring and molded follower are engineered to maintain consistent pressure and reliable alignment of cartridges for smooth chambering under rapid-fire or suppressed shooting conditions, while the steel body resists deformation from repeated insertion and outdoor use. Ruger branding and AR-556 model fit ensure compatibility and confidence for hunters, trainers, and recreational shooters who need extra capacity on hand without altering rifle performance. Whether used as a spare for tactical drills, varmint hunts with subsonic loads, or extended range sessions, this magazine balances durability and function for .300 Blackout platforms.
