PRO2A 5" 7.62x39 1/10 Micro Length NR Side Charging Melonite M-LOK AR-15 Upper Kit - Suppressor Ready

Product Description

Pack the immense kinetic signature of the legendary 7.62x39mm cartridge into an ultra-compact footprint optimized with modern manual manipulation controls. The PRO2A 5" 7.62x39 Micro Length Non-Reciprocating (NR) Side Charging Upper Kit introduces a high-speed charging layout that relocates weapon staging to a left-side lever, remaining static during firing cycles to preserve mechanical safety. Featuring a hard-hitting 5-inch 4150 CMV medium profile barrel, this assembly relies on a fine-tuned micro-length direct impingement gas system to cycle efficiently. The 1:10 twist rate ensures exceptional stability for standard 122gr to 124gr projectiles out of an ultra-short barrel profile. An abbreviated 4-inch free-float slim profile handguard exposes the muzzle threads completely, supplying zero rail-to-silencer clearance issues when pairing this platform with direct-thread or quick-attach suppressors. Arriving alongside a complete lower parts conversion package and an adjustable pistol blade, this turn-key system converts any standard stripped lower receiver into an elite compact platform.

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.
• Suppressor-Ready Clearance: An ultra-short 4-inch free-float rail stops clear of the muzzle threads, granting wide-open clearance to secure suppressors or custom muzzle systems directly onto the barrel without handguard interference.
• Heavy-Hitting 7.62x39 Caliber: Bridges the gap between sub-compact weapon dynamics and rifle-caliber kinetic signatures, providing devastating close-range velocity parameters.
• Premium QPQ Melonite Protection: Liquid bath nitride treatment hardens the 4150 Chrome Moly Vanadium core inside and out to maximize heat endurance, throat lifespan, and bad weather defense.
• Turn-Key Lower Completion Package: No piecemeal component tracking required; arrives complete with a full lower parts kit, fire control trigger group with an enhanced firing pin layout to reliably smash harder steel-cased primers, and an adjustable pistol blade assembly.

Why Choose This Product?

Running 7.62x39mm out of an ultra-short barrel profile traditionally creates extraction and mounting clearance issues for suppression tracking. Pro2A Tactical resolves this directly by pairing a precision-tuned micro-length gas layout with an enhanced firing pin, an exposed muzzle thread architecture, and a complete lower receiver build bundle. This configuration delivers an incredibly compact, dependable intermediate weapon package that drops seamlessly onto your existing AR-15 lower receiver setup.
