AKSA Arms S4 Model 12058 12 Gauge Semi-Auto Shotgun 18.5" 5+1 Chrome

The AKSA Arms S4 delivers reliable semi-automatic performance in a compact 12-gauge platform designed for tactical applications. This shotgun combines proven AK-style operating mechanics with modern materials and finishes for enhanced durability and corrosion resistance.

What Makes This Different

Unlike traditional shotguns, the S4 utilizes a gas-operated system derived from the AK platform, providing consistent cycling with both light and heavy loads. The 7075-T6 aluminum receiver offers 40% weight reduction compared to steel alternatives while maintaining structural integrity under high round counts. Chrome plating on critical surfaces extends service life and simplifies maintenance in harsh environments.
