PRO2A LEFT HAND 8.5" 300 Blackout 1/7 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can

Product Overview

The PRO2A LEFT HAND 8.5" 300 Blackout 1/7 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can maximizes short-barreled efficiency, blast mitigation, and shooter safety into a premium close-quarters layout. Chambered for versatile use with the .300 AAC Blackout cartridge, this true left-handed assembly utilizes a mirror-image left side ejection port to push expanding gas blowback and spent brass safely clear of southpaw eyes. It discards the standard rear charging handle for an ergonomic, Non-Reciprocating (NR) left-side charging interface. To tame the extreme muzzle blast and sound pressure inherent to short configurations, this model incorporates an integrated project-forward Flash Can muzzle device tucked cleanly beneath the handguard.

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 short-barrel muzzle blast by forcing sound pressure, thermal expansion, and aggressive concussive shock waves directly downrange away from the operator.
Ultra-Agile 8.5-Inch Profile: Dramatically minimizes overall length to optimize maneuvering speed in tight spaces, vehicular configurations, or dense home-defense environments while hitting the ballistic sweet spot for .300 BLK.
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?

Running a heavy cartridge like the 300 Blackout through a short 8.5-inch barrel typically creates a punishing concussive signature and noticeable muzzle flash. For a left-handed shooter on a standard right-hand upper, this means breathing in heavy exhaust gas while dodging spent shells. The PRO2A Left-Hand Side Charging Flash Can Upper elegantly addresses every single one of these operational hurdles. By combining a dedicated left-ejecting chassis with a project-forward linear flash can, noise and hot debris are pushed completely away from your eyes and ears.Choosing an 8.5-inch barrel length hits the absolute optimal envelope for the 300 BLK cartridge, maximizing velocity retention and complete powder burn without adding extra weight. Complete with a fluid, stationary side charging handle that allows fast manipulation without breaking your optic alignment, this assembly offers southpaw operators a smooth-cycling, ultra-compact powerhouse built to perform under pressure.
