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

Product Description

Maximize your medium-range knockdown power, terminal hard-hitting signature, and straight-wall compliance variables on standard AR-15 platforms with mirror-image ergonomics and advanced side-charging operation. The PRO2A LEFT HAND 16" 400 Legend Carbine Length Non-Reciprocating (NR) Side Charging 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. Built with an ergonomic right-side charging handle that remains stationary while firing and a left-hand ejection port, this upper allows shooters to maintain their sight picture, clear disruptions smoothly, and keep escaping gases and spent brass completely away from their face. The setup houses a 16-inch 4150 CMV medium profile barrel with a stable 1:16 twist rate to ensure maximum stabilization for heavy hunting loads. This turn-key 16"+ kit comes fully configured with everything required to finish your rifle build: the complete side-charging upper assembly, premium left-handed side-charging Bolt Carrier Group (BCG), 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 Ergonomics: Mirror-image billet design pairs right-side non-reciprocating charging handle mechanics with left-hand spent case ejection to provide full comfort and safety for southpaw shooters.
• Non-Reciprocating Side Charging Action: Billet-machined right-side charging handle provides superior mechanical leverage and remains stationary during live fire cycles, protecting the shooter and saving space under large hunting optics.
• Turn-Key 16"+ Rifle Build Setup: No piecemeal component tracking required; arrives complete with a left-handed side-charging upper assembly, specialized left-hand bolt carrier group, full lower parts kit, fire control trigger group, and a standard adjustable rifle stock assembly.
• High-Impact 400 Legend Caliber: Custom chambered to deploy Winchester's specialized straight-wall cartridge, maximizing downrange ballistics for modern deer and hog hunting landscapes.
• Specialized Straight-Wall Feed Optimization: Recoil and loading parameters are cleanly managed via a single large feed ramp configuration inside the receiver frame to combat case feeding friction.
• 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 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-hand platforms under large hunting scopes. Pro2A Tactical eliminates these structural variables entirely. By marrying a clean left-hand non-reciprocating side charging layout with a premium 16-inch Melonite barrel, a robust left-handed cartridge-matched bolt carrier group, and an all-inclusive lower receiver completion parts bundle in one cohesive package, you secure consistent sub-MOA groupings, uncompromising component integration, and professional reliability built right here in the USA.
