Elevate your hunting build and tactical weapon mechanics with the advanced ergonomics of side charging operation paired with maximized velocity scaling and a dedicated mirror-image layout. The PRO2A LEFT HAND 18" 400 Legend Carbine Length Non-Reciprocating (NR) Side Charging Upper Assembly delivers a modern, robust upper configuration designed explicitly for straight-walled cartridge profiles and left-handed operators. Featuring a right-side charging handle that remains stationary while firing and a left-hand ejection port, this upper allows shooters to maintain their sight picture, clear disruptions smoothly, and keep escaping gases and spent brass completely away from their face. Engineered around a premium, modified left-hand billet receiver optimized for Winchester's hard-hitting 400 Legend cartridge, it houses an 18-inch 4150 CMV medium profile barrel. The stable 1:16 twist rate guarantees maximum stabilization for heavy hunting loads, yielding exceptional downrange kinetic force and energy output at extended mediums.

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—an issue amplified for left-handed marksmen forced to use right-hand platforms. Pro2A Tactical solves this operational challenge entirely. By marrying a clean left-hand non-reciprocating side charging layout with an extended premium 18-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.
