PRO2A 5" 5.56 NATO 1/5 Micro Length NR Side Charging Melonite M-LOK AR-15 Upper Kit - Suppressor Ready

Product Description

Shrink your footprint to the absolute minimum while completely enhancing your manual weapon manipulation speed. The PRO2A 5" 5.56 NATO Micro Length Non-Reciprocating (NR) Side Charging Upper Kit introduces an advanced side-charging layout that relocates staging to a smooth, left-side lever, remaining static during live firing cycles to preserve absolute shooting 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 barrel utilizes an ultra-fast 1:5 twist rate to maximize rotational stabilization for heavy or short-barrel projectile trajectories, completely preventing keyholing out of a micro platform. 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 tool.

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-stop 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.
• Ultra-Fast 1:5 Twist Performance: Precision-engineered rotational torque stabilizes standard and heavy-grain 5.56/.223 projectiles cleanly out of a micro-length barrel profile.
• 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, and an adjustable pistol blade assembly.

Why Choose This Product?

Building a micro 5.56 PDW often causes gas cycling hesitation and handguard clearance issues when trying to pair it with a silencer. Pro2A Tactical fixes these structural hurdles completely. By matching a static, non-reciprocating side-charging upper action with a fast 1:5 twist barrel, an exposed muzzle thread architecture, and a complete lower receiver build bundle, this complete, American-made kit yields an uncompromised custom build right out of the box.
