The Century Arms CA-3 is a semi-automatic battle rifle patterned after the iconic HK G3, combining military surplus components with newly manufactured parts to deliver a modernized version of a classic 7.62 NATO platform. Chambered in 7.62x51 NATO, it features an 18" chromoly steel barrel, roller-delayed blowback system & stamped steel receiver compatible with claw mounts for optics. The rifle incorporates surplus Portuguese FMP parts such as the stock set, bolt carrier group & sights, paired with new U.S.-made components including the barrel, receiver and trunnion. With its rotary drum rear sight, fixed front post, and traditional G3 ergonomics, the CA-3 is designed for range shooting, historical enthusiasts and those seeking a cost-effective .308 battle rifle with classic styling. In terms of reliability and performance, the CA-3 benefits from the proven roller-delayed blowback system known for durability and consistent operation under harsh conditions. The combination of surplus military parts & modern manufacturing contributes to solid reliability, while the heavy 7.62 NATO chambering delivers strong ballistic performance & effective range. Although fit and finish may vary due to the use of surplus components, testing and evaluations show dependable function and respectable accuracy for a battle rifle platform. Overall, the CA-3 offers a robust and historically rooted shooting experience, backed by Century Arms’ role as a major importer of military-style firearms and its collaboration with manufacturers experienced in G3-type production.
