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

Product Description

Maximize your medium-range knockdown power, terminal hard-hitting signature, and straight-wall compliance variables on standard AR-15 platforms while maintaining absolute ergonomic safety. The PRO2A LEFT HAND 16" 400 Legend Carbine Length Melonite M-LOK Upper Assembly is expertly engineered from the ground up to handle the specific feeding requirements and robust case expansion dynamics of Winchester's 400 Legend hunting 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 a 16-inch 4150 CMV medium profile barrel. The stable 1:16 twist rate maximizes downrange projectile stabilization, delivering immense kinetic force 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, this assembly drops seamlessly onto your standard AR-15 lower receiver block.

Key Features

• True Left-Hand Ejection Architecture: Dedicated mirrored port arrangement completely eliminates cross-body brass throwing and concussive facial blowback for southpaw operators.
• High-Impact 400 Legend Caliber: Provides superior velocity scaling and terminal energy margins compared to legacy straight-wall choices, perfect for modern deer and hog hunting configurations.
• 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 a premium 16-inch Melonite barrel, this American-made upper receiver delivers maximum deer-dropping terminal energy and absolute safe-to-face field dependability right out of the box.
