The Century Arms CA-3 is a PTR-assembled G3-pattern rifle chambered for .308 Winchester and 7.62x51 NATO. Its roller-delayed blowback system combines military-surplus G3 components with new American-made parts, including a stamped steel receiver, trunnion, barrel, flash hider, hammer, sear, and charging handle. The rifle features a fixed stock, surplus forend, adjustable front sight, rotary aperture rear sight, and an 18-inch 4150 chromoly steel barrel threaded 5/8x24. The claw-mount-compatible receiver allows compatible optics to be added while preserving the rifle’s classic battle-rifle configuration.
