Maximize your velocity and intermediate-range performance with the Pro2A Tactical 18" 7.62x39 Carbine Length Melonite M-LOK Upper. Combining the hard-hitting terminal physics of the traditional 7.62x39mm round with the modular versatility of the AR-15 platform, this complete upper receiver features a heavy-duty 18-inch Melonite barrel with a precise 1:10 twist rate. Powered by a robust carbine-length gas system to ensure high-pressure cycling, this upper comes paired with a rigid, free-float M-LOK handguard that completely isolates the barrel. It is the ultimate choice for medium-game hunting, target shooting, and custom long-barrel utility rifle builds without NFA restrictions.
Stepping up to an 18-inch barrel length yields a distinct ballistic edge over shorter platforms. It allows for a more complete propellant burn from the 7.62x39mm cartridge, boosting muzzle velocity to squeeze extra distance and flatter trajectories out of your hunting loads. It gives you maximum kinetic energy downrange, delivering massive energy on target for an ethical harvest of deer and feral hogs.
Built to handle extensive high-volume ranges and rough outdoor environments, 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 backcountry 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. Simply drop in a dedicated 7.62x39 Bolt Carrier Group (BCG) and your choice of charging handle to transform your lower receiver into a heavy-hitting field rifle.
