PRO2A LEFT HAND 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 elevating left-handed tactical controls and mechanical manual operation speed. The PRO2A LEFT HAND 5" 5.56 NATO Micro Length Non-Reciprocating (NR) Side Charging Upper Kit delivers uncompromised southpaw ergonomics on an ultra-compact Personal Defense Weapon (PDW) blueprint. By pairing a true left-ejecting action with a side-charging mechanism that remains completely static while firing, this assembly routes gas pressure and spent casings safely down the left side, entirely removing facial blowback. The 5-inch 4150 CMV barrel features 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, ensuring clean structural real estate to directly mount quick-attach or direct-thread suppressors without rail-to-silencer interference. Complete with all lower receiver completion components and an adjustable pistol blade assembly, this turn-key package upgrades your stripped lower into an elite compact tool.

Key Features

• True Left-Hand Ejection: Dedicated mirrored port arrangement completely eliminates cross-body brass throwing and concussive facial blowback for southpaw operators.
• Non-Reciprocating Side Charging Action: Left-side charging mechanism permits fast weapon charging while keeping your eyes fixed on target and remains entirely stationary when 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.

Why Choose This Product?

Building a micro 5.56 PDW often causes stabilization and rail clearance headaches when mounting a silencer, and the gas blowback is heavily amplified for left-handed operators running standard setups. Pro2A Tactical fixes these structural hurdles completely. By matching a true mirrored left-ejection, non-reciprocating side-charging upper action with a fast 1:5 twist barrel and an exposed muzzle thread architecture, this complete, American-made kit yields an uncompromised custom build right out of the box.
