Century Arms CA-3 7.62x51mm NATO 18" 20+1 Semi-Auto Rifle

The Century Arms CA-3 is a 7.62x51mm NATO semi-auto battle rifle built on the iconic G3 roller-delayed blowback platform. Assembled by PTR, this rifle blends original surplus G3 components with new American-made parts to deliver a faithful, shootable recreation of the legendary military battle rifle.

An 18" threaded barrel with a 1:10 twist and an A2 birdcage flash hider gives the CA-3 its classic battle rifle profile. The barrel is threaded 5/8x24 for easy mounting of a suppressor or muzzle brake. An adjustable front post sight pairs with a rotary aperture rear sight for accurate shooting right out of the box.

The rifle rides on a stamped steel receiver finished in black, paired with a black synthetic fixed stock and forend for that traditional G3 silhouette. Overall length is 40.50" and weight is 9.50 lbs. The CA-3 feeds from a detachable 20-round magazine and uses the proven roller-delayed blowback operating system that made the G3 a worldwide military standard.

This configuration ships with new American-made components from PTR, including the trunnion, barrel, flash hider, stamped receiver, hammer, sear, and charging handle, paired with original surplus parts for the fixed stock, forend, adjustable front sight, rotary aperture rear sight, trigger group (modified for compliance), bolt, and bolt carrier. The result is a battle rifle that captures the spirit of the original G3 while meeting modern manufacturing standards.
