PRO2A 8.5" 7.62x39 1/10 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper Kit with Flash Can

Product Description

Pack the severe close-quarters impact of the standard 7.62x39mm cartridge into an exceptionally compact platform while taming intense muzzle concussions, elevating mechanical weapon manipulation controls, and removing individual component matching guesswork. The PRO2A 8.5" 7.62x39 Pistol Length NR Side Charging Melonite M-LOK Upper Kit with Flash Can provides an all-inclusive build package engineered to route harsh explosive sound waves and visual muzzle blast straight downrange away from the operator. Shifting away from a traditional rear charging design, it implements a left-side non-reciprocating side charging handle layout that remains completely stationary while live rounds cycle, preserving absolute shooting safety and protecting the operator's forward hand grip. Built around a premium billet aluminum receiver with a standard right-side ejection port, this setup houses an agile 8.5-inch 4150 CMV medium profile barrel with a 1:10 twist rate optimized to cleanly stabilize standard weight 122gr to 124gr factory loads. The integrated slimline flash can muzzle device sits recessed beneath an extended free-float M-LOK rail system, allowing for a continuous, comfortable hand grip. Operating on a fine-tuned pistol gas layout, this turn-key platform arrives completely paired with a heavy-duty side-charge bolt carrier group upgraded with an enhanced firing pin for absolute steel-case primer ignition, a complete lower parts kit, and an adjustable pistol stabilizing blade extension assembly.

Key Features

Non-Reciprocating Side Charging Action: Intuitively positioned on the left side of the receiver, this mechanism lets you cycle the bolt while keeping your hand secure on the main pistol grip, staying completely fixed during live cycling to prevent handguard interference or sight-picture disruption.
Concussive Control Flash Can: Recessed muzzle configuration directs intense close-quarter muzzle blast, acoustic shockwaves, and primary flash forward downrange and completely away from the shooter's ears.
Steel Case Primer Reliability: Included side-charging bolt carrier group features an enhanced, extended-tip firing pin engineered explicitly to reliably ignite harder military-grade steel-cased primers.
Tuned Pistol-Length Gas Curve: Optimizes internal gas expansion velocity and dwell times to deliver flat, uniform mechanical cycling profiles with a wide variety of factory intermediate ammunition.
Turn-Key Lower Completion Package: Arrives complete with a non-reciprocating side-charge extended rail upper assembly, enhanced side-charge firing pin BCG, full lower parts kit, fire control trigger group, and an adjustable pistol blade extension assembly.

Why Choose This Product?

Firing full-powered rifle loads out of shorter barrel profiles creates severe side-blast concussion that can disrupt close-quarters focus, while hard military primers frequently cause ignition failures. Pro2A Tactical resolves these structural hurdles completely. By matching an extended free-float handguard around a specialized forward-directing flash can, integrating a premium static side charger with an enhanced deep-striking firing pin, and packing an all-inclusive lower receiver build group, this complete, American-made kit yields rapid manual manipulation controls without breaking your cheek weld or target focus, bringing absolute field reliability and excellent shooting comfort right out of the box.
