PRO2A LEFT HAND 18" 400 Legend 1/16 Carbine Length Melonite M-LOK AR-15 Upper

Product Description

Maximize your medium-range knockdown power, muzzle velocity scaling, and straight-wall compliance parameters on standard AR-15 platforms while maintaining absolute ergonomic safety. The PRO2A LEFT HAND 18" 400 Legend Carbine Length Melonite M-LOK Upper Assembly is expertly engineered from the ground up to unlock the full potential of Winchester's heavy-hitting straight-walled cartridge, tailored natively for southpaw operators. Utilizing a mirrored left-ejecting receiver profile, this system completely removes cross-body brass throwing and facial carbon gas blowback common when lefties run traditional right-handed configurations with large straight-wall cases. Constructed with specialized feed geometry tailored cleanly for thick, heavy straight-walled ammunition, this setup houses an 18-inch 4150 CMV medium profile barrel. The extended barrel length ensures a complete powder burn, delivering a clear velocity premium over shorter configurations to flatten downrange paths out to 200 yards. Tuned precisely with a reliable direct impingement carbine gas layout and a low-profile gas block to produce smooth cyclic curves.

Key Features

• True Left-Hand Ejection Architecture: Dedicated mirrored port arrangement completely eliminates cross-body brass throwing and concussive facial blowback for southpaw operators.
• Optimized 18-Inch Hunting Velocity: Elongated straight-wall barrel structure squeezes extra velocity metrics out of commercial hunting loads, delivering flat trajectories over extended medium-range distances.
• Specialized Feed Profiling Receiver: Engineered specifically to cycle heavy straight-walled cartridge bodies cleanly and repeatedly without the feeding failures common in unoptimized setups.
• Resilient Free-Float M-LOK Architecture: Premium 15-inch slim profile aluminum rail isolates the barrel from external handling pressure vectors, ensuring continuous point-of-impact accuracy.
• Liquid Bath Nitride Protection: Full interior and exterior QPQ Melonite barrel coating provides maximum resistance to heat friction, extreme weather elements, and throat erosion.

Why Choose This Product?

Hunting inside strict straight-wall restricted states traditionally forced southpaw builders into severe compromises over case blowback hazards or semi-automatic reliability thresholds. Pro2A Tactical eliminates these construction variables entirely. By pairing an expertly profiled feed channel left-handed receiver with an elongated 18-inch Melonite core barrel, this American-made upper receiver delivers maximum deer-dropping terminal energy and absolute safe-to-face field dependability right out of the box.
