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

Product Description

Shrink your footprint to the absolute minimum while enhancing manual manipulation. The PRO2A 5" 5.56 NATO Micro Length Non-Reciprocating (NR) Side Charging Upper introduces a high-speed charging layout that relocates weapon staging to a left-side lever, remaining static during live firing cycles to preserve mechanical safety. Featuring a 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, 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.

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.
• 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.
• 100% Made in the USA: Assembled from high-grade aircraft billet and forged components to rigorous manufacturing tolerances in Georgia, backed by premium custom-shop engineering quality.

Why Choose This Product?

Building a micro 5.56 PDW often causes stabilization and rail clearance headaches when mounting 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 and an exposed muzzle thread architecture, this American-made assembly delivers smooth ergonomic handling and extreme compact maneuverability that is compatible with any standard AR-15 lower receiver setup.
