Product Overview

The PRO2A LEFT HAND 16" 350 Legend 1/16 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper Kit is a fully comprehensive, mirror-engineered master build package purpose-built to deliver premium ergonomics and high-impact cycling for left-handed operators. Centered around a **Left-Eject Non-Reciprocating (NR) side-charging billet receiver**, this system isolates manual handle movement from internal cycling parameters while routing spent straight-wall casings safely away from southpaw operators. The full 16-inch barrel configuration extracts massive downrange energy out of the .350 Legend cartridge while remaining compliant with traditional straight-wall deer hunting regulations and non-NFA rifle setups. Fully populated with a matching left-handed full-auto profile bolt carrier group, dedicated side-charging handle assembly, reliable carbine-length gas loop, complete lower parts matrix, and an adjustable rifle stock assembly, this kit removes all component matching guesswork entirely.

Key Features

• All-In-One Complete Kit Pipeline: Consolidates your entire shopping list by providing the internal left-hand cycling mechanics, fire control group, lower frame small parts, and stock kit furniture inside one premium assembly order.
• True Left-Hand Architecture: Engineered with a dedicated left-side ejection port to prevent face-directed hot straight-wall brass and gas blowback exposure for southpaw shooters.
• Non-Reciprocating Right-Side Ergonomics: The charging handle stays completely stationary when firing, preserving your optic sight lines, mitigating optical obstruction, and accelerating manual cycle workflows under high leverage.
• Optimized Straight-Wall Hunting Ballistics: The 16-inch barrel structure offers exceptional projectile velocity, maximizing flat downrange performance and hard-hitting energy metrics for legal straight-wall field hunting.
• Precision 1:16 Twist Stabilization: Explicitly bored to ensure flawless rotational stabilization for traditional 150gr to 180gr commercial hunting and defense projectiles.
• Sub-Surface Melonite QPQ Armor: Liquid-immersion nitriding infuses deep surface protection across the 4150 CMV steel barrel core, safeguarding critical lands and grooves from harsh throat attrition and environmental humidity.
• Free-Floating M-LOK Handguard: Features a slim-profile modular rail system aligned flat with the upper receiver top rail, optimizing accessory and bipod placement without shifting your barrel's point of impact.

Why Choose This Product

Choosing this complete 16-inch .350 Legend left-handed kit modernizes the hunting rifle pipeline for southpaws who refuse to compromise with standard right-hand controls. Combining a dedicated left-eject receiver pathway with a stationary left-side charging lever entirely cradles the operator from facial gas blowback and unnatural workspace manipulation. Furthermore, modified feed pathways and face-opened bolts ensure reliable cycling with non-bottlenecked casings, eliminating nose-diving malfunctions out of the box. Packed with premium treated components from the full-auto profile tracking group down to the polished lower fire control links, this kit represents the absolute peak of custom hunting value. Proudly manufactured 100% in the USA from heavy-duty raw metals.
