Why Choose This Product?

For left-handed deer hunters and marksmen operating under straight-wall legislative limits, the 350 Legend cartridge provides an exceptional balance of low recoil and massive kinetic transfer. However, traditional right-hand setups force left-handed shooters to deal with gas blowback directly in their line of sight. This PRO2A Left-Hand Upper eliminates this safety hazard and ergonomic headache entirely, mirroring the platform layout perfectly for southpaw comfort.

Traditional rear charging handles force you to break your cheek weld and drop out of your optical plane just to manipulate the bolt—a flaw amplified when running large hunting optics. The PRO2A 20" Side Charging Upper eliminates this roadblock entirely, providing a fluid side-charging configuration that lets you cycle the action comfortably while staying completely locked onto your downrange target.While shorter barrels restrict full propellant combustion, this full 20-inch rifle-length configuration coaxes optimal muzzle velocity, extreme accuracy, and maximized terminal expansion profiles out of your cartridge. Enveloped in an ultra-durable QPQ Melonite anti-corrosion barrier, matched with a rigid billet receiver, and finished with a lightweight free-float M-LOK rail system, this drop-in platform strips away configuration headaches to give left-handed shooters a clean-cycling precision powerhouse built for severe service straight out of the box.
