Elevate your hunting build and tactical weapon mechanics with the advanced ergonomics of side charging operation. The PRO2A 16" 400 Legend Carbine Length Non-Reciprocating (NR) Side Charging Upper Assembly delivers a modern, robust upper configuration designed explicitly for straight-walled cartridge profiles. Built with an ergonomic left-side charging handle that remains stationary while firing, this upper allows operators to maintain their sight picture and clear disruptions smoothly without manipulating a traditional rear charging handle under large optics configurations. Engineered around a premium, modified billet receiver optimized for Winchester's hard-hitting 400 Legend cartridge, it houses a 16-inch 4150 CMV medium profile barrel. The stable 1:16 twist rate guarantees maximum stabilization for heavy hunting loads, yielding exceptional kinetic terminal force out to medium ranges.

Traditional rear charging handles often conflict with the low-profile mounts and thick turrets of modern hunting optics, introducing manipulation lag during fast follow-up shots. Pro2A Tactical solves this operational challenge entirely. By marrying a clean non-reciprocating side charging layout with a premium 16-inch Melonite barrel and a specialized straight-wall feeding upper receiver, this configuration maximizes your tactical leverage, ensures relentless extraction cycles in extreme hunting elements, and guarantees premium performance engineered to outlast standard builds.
