Achieve maximum velocity and full compliance in straight-walled hunting states with the PRO2A LEFT HAND 16" 350 Legend Upper Kit. Engineered natively from the ground up for left-handed operators, this rifle-length configuration utilizes a mirrored left-ejecting receiver profile and dedicated left-hand M16 bolt carrier group to redirect hot gas and spent casings safely away from your face. The 16-inch medium profile barrel optimizes powder burn for the hard-hitting 350 Legend cartridge, while the carbine-length gas system guarantees smooth, consistent cycling. This comprehensive package includes all the build components necessary to transform your standard stripped lower receiver into a premier southpaw hunting rifle.
