PRO2A LEFT HAND 16" 300 Blackout 1/7 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can

Product Overview

The PRO2A LEFT HAND 16" 300 Blackout 1/7 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can delivers a highly functional rifle solution with elite ergonomics for southpaw shooters. Chambered in the hard-hitting .300 AAC Blackout cartridge, this complete upper receiver assembly combines a non-reciprocating side-charging interface with a true left-hand ejection design to keep gases and hot spent brass entirely away from your sightlines. To tame the raw blast signature inherent to short-gas setups, it features an integrated blast-forwarding Flash Can muzzle device tucked neatly inside the free-float rail. This configuration yields maximum velocity retention from a full-length 16-inch barrel without NFA restrictions, offering a clean-cycling, ultra-reliable foundation for hunting, defensive work, or range performance.

Key Features

True Left-Hand Ejection Architecture: Left-side ejecting configuration paired with a matched left-handed bolt carrier group safely redirects carbon blowback and blistering spent casings entirely out of southpaw sightlines.
Non-Reciprocating Side Charging: Fluid manual control handle remains completely stationary while the action cycles, giving you effortless structural clearance for optics and lasers without moving parts near your hand.
Linear Flash Can Muzzle Device: Tames severe gas concussion by forcing sound pressure, thermal expansion, and aggressive shock waves directly downrange and away from the operator.
Full 16-Inch Rifle Profile: Squeezes maximum ballistic performance and complete muzzle velocity profiles out of supersonic .300 BLK ammunition without the need for tax stamps or SBR registration.
Fast 1/7 Twist Rifling: Precision-engineered twist profile ensures excellent stabilization across a versatile array of bullet weights, effortlessly cycling light supersonic ammo and heavy subsonic loads alike.
QPQ Melonite Protective Finish: Premium Salt Bath Nitride coating hardens internal rifling and external steel surfaces to provide excellent friction reduction and all-weather corrosion defense.

Why Choose This Product?

Traditional right-handed rifles compromise a southpaw operator's comfort by spraying hot gas, debris, and abrasive carbon blast right across their line of sight, an issue that is heavily amplified when firing intermediate cartridges like the 300 Blackout. The PRO2A Left Hand 16" Side Charging Upper removes these limitations entirely. By integrating a dedicated left-ejecting chassis with a stationary, non-reciprocating side charger, you can cycle the weapon naturally from the shoulder without breaking your optical alignment or losing your cheek weld.Configured with a full 16-inch barrel length, this upper ensures simple, hassle-free rifle assembly without NFA restrictions, making it an excellent platform for a tactical utility tool, hunting setup, or home-defense system. To further maximize user comfort, the integrated linear flash can channels sound pressure directly downrange away from your ears. Backed by heavy-duty 4150 steel construction, a high-durability Melonite finish, and a fast 1/7 twist rate built to stabilize heavy subsonic defensive loads and standard supersonic ammunition alike, this upper receiver assembly delivers a clean, reliable, and entirely uncompromised tactical upgrade straight out of the box.
