Enjoy hard-hitting, cost-effective performance with the Pro2A Tactical 16" 7.62x39 Carbine Length Melonite M-LOK Upper. Melding the devastating terminal ballistics of the classic 7.62x39mm round with the modular ergonomics of the AR-15 platform, this complete upper receiver features a heavy-duty 16-inch Melonite barrel with a precise 1:10 twist rate. Driven by a highly reliable carbine-length gas system to guarantee robust cycling, this upper comes paired with a rigid, free-float M-LOK handguard that completely isolates the barrel. It is the perfect plug-and-play choice for medium-game hunting, budget-friendly range training, and home defense setups without any NFA restrictions.
The 7.62x39mm round is legendary for its raw stopping power and excellent barrier penetration. This 16-inch barrel configuration maximizes propellant efficiency, delivering near-.30-30 Winchester energy out of a standard AR-15 footprint. It makes an outstanding, budget-friendly medium-game hunting rifle for deer and feral hogs, packing significantly more close-to-medium-range kinetic punch than traditional small-bore alternatives.
Because much of the surplus ammunition on the market can be tough on components, our Melonite-finished barrel utilizes an advanced QPQ liquid nitriding surface treatment. This chemical process hardens the steel on a molecular level both inside the bore and on the exterior profile. The result is class-leading wear resistance against intense firing schedules and elite defense against rust, all while preserving match-grade downrange accuracy.
Protect your zero from external resting force. The sleek, free-floating M-LOK handguard securely mounts to the barrel nut, keeping your bipod pressure or barricade rests from warping natural barrel harmonics. Outfitted with precision M-LOK cutouts at the 3, 6, and 9 o'clock positions, mounting tactical lights, weapon lasers, and vertical grips is entirely clean and modular.
Every single component in this upper assembly is machined from top-tier materials. The upper receiver is forged from rugged 7075-T6 aluminum and features precision-cut feed ramps optimized to guarantee smooth feeding and reliable extraction right out of the box. Drop in a dedicated 7.62x39 Bolt Carrier Group (BCG) and your favorite charging handle to instantly transform your lower receiver into a high-powered rifle system.
