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

Product Description

Maximize your medium-range knockdown power, terminal velocity scaling, and straight-wall compliance variables on standard AR-15 platforms with mirror-image ergonomics. The PRO2A LEFT HAND 18" 400 Legend Carbine Length Melonite M-LOK Upper Kit provides an all-inclusive rifle completion package engineered specifically to handle the structural feeding requirements and robust case expansion dynamics of Winchester's 400 Legend hunting cartridge—optimized explicitly for left-handed operators. Constructed around a premium left-hand ejecting forged 7075-T6 aluminum receiver with specialized feed geometry tailored cleanly for thick, heavy straight-walled ammunition, this setup houses an 18-inch 4150 CMV medium profile barrel. The stable 1:16 twist rate maximizes downrange projectile stabilization, delivering immense kinetic force out to extended distances while keeping escaping gases and spent brass away from your face. Operating on a tuned carbine-length direct impingement gas setup to produce smooth cyclic curves, this turn-key platform arrives completely paired with a premium left-handed cartridge-matched bolt carrier group, full lower parts conversion kit, and an adjustable stock assembly. Drop these components into your standard stripped lower receiver to finish your ultimate left-handed straight-wall deer or hog tracking hunting rifle.

Key Features

• True Left-Hand Ejection: Dedicated mirror-image upper receiver layout keeps hot spent cases and blowback gases out of the left-handed shooter's line of sight.
• 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.
• Turn-Key Rifle Build Setup: No piecemeal component tracking required; arrives complete with a left-handed upper assembly, specialized left-hand bolt carrier group, charging handle, full lower parts kit, fire control trigger group, and a standard adjustable rifle stock assembly.

Why Choose This Product?

Hunting within strict straight-wall restricted zones often introduces feeding friction and cycling hesitation when running unoptimized standard AR setups—an issue amplified for left-handed marksmen forced to use right-handed platforms. Pro2A Tactical eliminates these structural variables entirely. By pairing a dedicated left-hand feed ramp receiver upper with a premium 18-inch Melonite barrel, a robust left-handed cartridge-matched bolt carrier group, and an all-inclusive rifle stock bundle in one cohesive package, you secure consistent sub-MOA groupings, uncompromising component integration, and professional reliability built right here in the USA.
