PRO2A LEFT HAND 10.5" 7.62x39 1/10 Carbine Length Melonite M-LOK AR-15 Upper

Description

The Pro2A Tactical Left-Handed 10.5-inch 7.62x39mm Complete Upper Receiver assembly packs heavy-hitting caliber ballistics into an agile, highly balanced layout engineered specifically for southpaw operators. Hand-assembled and quality verified in Georgia, this upper receiver structure replaces the traditional right-eject configuration with a dedicated left-side ejection port. Utilizing an optimized 10.5-inch Melonite treated barrel and a reliable carbine-length direct impingement gas system, it provides a premium drop-in solution for close-quarters platforms, specialized pistol lower frames, or registered short-barreled rifles.

Key Features

True Left-Handed Ergonomics: Features a dedicated left-side ejection port configuration that protects southpaw shooters from exhausting muzzle gases, facial blowback, and flying spent casings.
Optimized 10.5" Velocity Curve: Delivers superior powder burn efficiency and increased muzzle velocity compared to shorter micro layouts while maintaining an incredibly compact handling chassis.
Versatile 1/10 Twist Rate: Precision spun to stabilize standard 122gr, 123gr, and heavy sub-sonic grain weights comfortably for reliable downrange tracking.
Slim Profile M-LOK Handguard: Wrapped in a lightweight 9-inch free-float rail system that preserves barrel accuracy while maximizing modular mounting surfaces for tactical accessories.

Why Choose This Product?

Building a high-performance, short-barreled 7.62x39 platform often forces left-handed operators to swallow intense gas blowback or manage erratic extraction patterns across their face. The Pro2A Left Hand 10.5" Upper addresses these layout limitations completely by pairing a factory-headspaced left-hand bolt carrier group configuration with an enhanced feed ramp geometry optimized for flawless cyclic reliability. Coated inside and out in an ultra-hard Melonite treatment for unmatched corrosion defense and simplified cleaning cycles, it is the ultimate upgrade option for southpaw marksmen looking for portable large-bore dominance.
