PRO2A LEFT HAND 18" 7.62x39 1/10 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper

Description

The Pro2A Tactical Left-Handed 18-inch 7.62x39mm Non-Reciprocating (NR) Side Charging Complete Upper Receiver assembly maximizes muzzle velocity, downrange terminal energy, and smooth southpaw ergonomics on the AR-15 platform. Hand-assembled and quality verified in Georgia, this premier system integrates a true left-ejecting receiver profile with an advanced, static side-charging mechanism. Paired with an extended 18-inch barrel profile that unlocks the full ballistic capability of the 7.62x39mm cartridge and a reliable carbine gas curve, it delivers a high-performance, blowback-free drop-in solution built for hunting, target, or defensive rifle applications.

Key Features

• Left-Handed Non-Reciprocating Control: Features a dedicated left-eject billet receiver paired with a side-mounted charging handle that remains static while firing, preventing optical interference and redirecting high-pressure port gases away from the shooter's face.
• Extended 18-Inch Ballistics: Maximizes powder burn efficiency to push muzzle velocities and kinetic performance to its absolute limit, providing superior long-range tracking compared to shorter carbines.
• Versatile 1/10 Twist Rate: Precision spun to comfortably stabilize standard 122gr and 123gr loads, alongside heavy supersonic and subsonic variants for elite downrange consistency.
• Premium Melonite Hardness: The 4150 steel barrel is treated inside and out with an ultra-hard Melonite finish, providing extreme corrosion resistance and an easily cleaned bore surface.

Why Choose This Product?

Running a standard right-ejecting rifle platform with large-bore ammo like the 7.62x39 cartridge often forces left-handed operators to breathe in exhausting port gases or deal with stray brass crossing their field of vision. The Pro2A Left Hand 18" NR Side Charging Upper Receiver solves left-handed extraction compromises completely by pairing its premium billet architecture with a perfectly headspaced left-hand bolt configuration and an enhanced firing pin optimized for hard primers. The static side-charging handle yields crucial clearance for modern, oversized optics while significantly improving operational leverage from prone or benched shooting stances. It is the definitive drop-in upgrade for southpaw shooters demanding absolute mechanical rigidity.
