PRO2A LEFT HAND 5" 5.56 NATO 1/5 Micro Length Melonite M-LOK AR-15 Upper Kit - Suppressor Ready

Product Description

Shrink your footprint to the absolute minimum without traditional mechanical blowback or component matching guesswork. The PRO2A LEFT HAND 5" 5.56 NATO Micro Length Upper Kit delivers premium Personal Defense Weapon (PDW) engineering in a complete, all-inclusive build layout built natively for southpaw operators. Utilizing a mirrored left-ejecting receiver profile and a matching left-hand M16 bolt carrier group, this assembly routes gas pressure and spent casings safely down the left side, entirely removing facial blowback. Featuring a 5-inch 4150 CMV medium profile barrel, this assembly utilizes an ultra-fast 1:5 twist rate to maximize rotational stabilization for lightweight or heavy-grain 5.56/.223 projectiles, preventing keyholing out of short setups. The barrel threads are left completely accessible by an abbreviated 4-inch free-float slim profile handguard, giving you clean clearance to directly screw on quick-attach or direct-thread suppressors. Bundled alongside a full lower parts kit and a high-density stabilizing blade package, this turnkey system converts any standard stripped lower receiver into an elite compact tool.

Key Features

• True Left-Hand Architecture: Dedicated mirrored left-ejection port setup keeps hot casings, structural debris, and aggressive gas blowback completely away from left-handed operators.
• Ultra-Fast 1:5 Twist Rate: Precision-engineered rotational torque stabilizes standard and heavy-grain 5.56/.223 projectiles cleanly out of a micro-length barrel profile.
• Suppressor-Ready Clearance: A compact 4-inch M-LOK handguard leaves muzzle threads entirely exposed, allowing seamless mounting and removal of suppressors and muzzle accessories without rail interference.
• Fine-Tuned Micro Gas Management: Specialized micro-length direct impingement gas system provides predictable dwell times and smooth cycling pressure curves with factory ammunition.
• 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 an ultra-short 5.56 PDW often introduces gas cycling hesitation and handguard clearance issues when trying to pair it with a silencer, and the facial blowback can be blinding for a lefty shooter. Pro2A Tactical simplifies this process entirely. By matching a true mirrored left-ejection action and a premium 5-inch fast-twist barrel with an exposed muzzle thread architecture, a short 4-inch M-LOK handguard, and a complete lower receiver build bundle, this American-made kit yields an uncompromised custom build right out of the box.
