Product Overview

The PRO2A LEFT HAND 7.5" 223/5.56 1/7 Pistol Length Melonite M-LOK AR-15 Upper is a mirror-engineered, standalone top-end assembly purpose-built to deliver premium ergonomics for left-handed operators. Centered around a **dedicated Left-Eject forged receiver**, this assembly completely moves the spent casing trajectory and hot blast gases away from standard layouts to keep them safely clear of left-dominant shooters. The 7.5-inch micro barrel length offers the ultimate in ultra-compact agility, serving as the perfect foundation for a highly responsive close-quarters firearm project.

Key Features

• True Left-Hand Architecture: Engineered with a dedicated left-side ejection port to prevent face-directed hot brass and gas blowback exposure for southpaw shooters.
• Ultra-Compact Micro Profile: Hard-hitting 7.5-inch barrel structure brings maximum tactical mobility and rapid manipulation to close-quarters tactical platforms.
• Military-Grade 1:7 Twist Profile: Highly optimized to reliably stabilize heavier tactical projectiles (such as 62gr, 69gr, and 77gr duty loads) even over shorter micro-length barrels.
• 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 placement without shifting your barrel's point of impact.

Why Choose This Product

This standalone 7.5-inch barreled upper receiver assembly provides a highly specialized platform that completely modernizes left-handed shooting dynamics for ultra-compact builds. Transitioning weapon indexing to a left-ejecting path removes the awkward gas-in-the-face exposure common to southpaws operating standard configurations. By focusing purely on the core barreled receiver assembly, this layout allows you to drop in your choice of a dedicated left-handed bolt carrier group and preferred charging handle without paying for unneeded lower package components. Proudly manufactured in the USA to unrelenting tactical tolerances, it delivers reliable field accuracy right out of the box.
