Century Arms RI5601AX CA-3 7.62x51mm NATO 20+1 18" Black Threaded Barrel, Black Steel Receiver, Fixed Black Synthetic Stock & Grip, A2 Birdcage Flash Hider

The Century Arms RI5601AX CA-3 is a 7.62x51mm NATO rifle built on the proven roller-delayed blowback platform of the classic G3 design. This semi-automatic rifle combines authentic surplus components with new American-made parts, giving you a rugged, reliable platform at a practical price point. If you're a shooter who values proven mechanical simplicity, proven durability, and the ability to shoot a full-power rifle round without breaking the bank, the CA-3 delivers all three.

The rifle ships with an 18-inch barrel threaded for muzzle devices and topped with an A2-style flash hider. The black steel receiver is paired with a fixed synthetic stock and grip for a no-frills, ergonomic shooting experience. You'll get a single 20-round magazine, adjustable front sight, and a rotary aperture rear sight, so you're ready to shoot out of the box—no layaway for optics required, though the sight radius and NATO standard receiver will accommodate future upgrades if you choose them.

Built for hunters, target shooters, and anyone who respects the reliability of battle-tested rifle mechanics, the CA-3 handles 7.62x51mm NATO ammunition—a cartridge known for flat trajectory, hard-hitting performance, and broad commercial availability. The roller-delayed system cycles smoothly and reduces felt recoil compared to direct-impingement designs, making it friendly for extended range sessions or hunting days in the field.
