PRO2A LEFT HAND 22" 5.56 NATO 1/7 Rifle Length Melonite M-LOK AR-15 Upper

Product Overview

The PRO2A LEFT HAND 22" 5.56 NATO 1/7 Rifle Length Melonite M-LOK AR-15 Upper is custom-engineered to unlock maximum velocity and extreme distance accuracy for southpaw shooters. Featuring an extended 22-inch premium steel barrel, this complete upper receiver assembly delivers a true left-ejecting layout that channels high-pressure carbon blowback and blinding brass away from your sightlines. Built with a smooth-cycling, full rifle-length gas system and an aggressive 1/7 twist rate, this top-tier assembly provides an uncompromised precision platform optimized for varmint hunting, benchrest competition, or long-range tactical setups.

Key Features

True Left-Hand Architecture: Mirrored left-ejecting receiver profile paired with a matched left-hand bolt carrier group routes high-pressure carbon blowback and blistering spent shells safely clear of left-dominant eyes.
Extended 22-Inch Velocity Footprint: Exceptional 22-inch barrel length squeezes every ounce of muzzle velocity out of the 5.56 NATO cartridge, significantly flattening trajectories and maximizing downstream terminal energy.
Fast 1/7 Twist Rifling: Precision-rifled profile engineered to provide exceptional rotational stabilization for heavy grain tactical and match-grade projectiles (62gr, 69gr, and 77gr).
QPQ Melonite Case Hardening: Highly durable Salt Bath Nitride treatment shields the internal bore and outer barrel surfaces against friction wear, intense thermal spikes, and damp field conditions.
Ultra-Smooth Rifle Gas Calibration: Full-length rifle gas layout reduces port pressure spikes to deliver the softest recoil impulse possible, maximizing shooter tracking during long-range deployment.
Free-Float Slim M-LOK Handguard: Enhances intrinsic accuracy by isolating barrel harmonics, providing a top Picatinny rail and clear M-LOK attachment slots for bipods and optics.

Why Choose This Product?

Traditional right-handed precision rifles heavily compromise a southpaw operator's focus by spraying hot gas, unburnt powder, and spent shells across their line of sight. The PRO2A Left Hand 22" Upper eliminates this compromise entirely, routing debris safely to the left so you can stay fully locked on target.

While standard 16-inch barrels lose velocity over extended distances, this extended 22-inch Melonite barrel ensures complete powder burn, driving bullets faster and flattening your long-range trajectory. Backed by a full rifle-length gas system that stretches out the pressure curve to deliver a remarkably soft recoil impulse, this complete upper receiver assembly offers southpaw marksmen an uncompromised, exceptionally clean-cycling, and ultra-accurate long-range powerhouse straight out of the box.
