PRO2A LEFT HAND 14.5" 5.56 NATO 1/7 Mid Length Melonite M-LOK AR-15 Upper with Flash Can

True Left-Handed Ejection Performance Paired with Forward Blast Diversion

Engineered to deliver ultimate operational comfort, clear visibility, and massive blast reduction for left-dominant operators. The PRO2A Left Hand 14.5" 5.56 NATO Mid-Length Melonite Upper with Flash Can optimizes the standard AR-15 footprint for Southpaw shooters. By mirroring the physical ejection path to the left side, this upper routes scorching gases, unburnt powder residue, and spent brass completely away from your face. Built around a versatile 14.5-inch 4150 CMV steel barrel, it is paired with an integrated linear flash can recessed underneath an extended handguard. The flash can captures high-pressure muzzle concussion and pushes it straight downrange away from the shooter. This complete receiver setup arrives ready to accept your preferred left-handed bolt carrier group and charging handle, mounting natively to any standard Mil-Spec AR-15 lower receiver. Proudly 100% designed, machined, and precision-tested in the USA.

Key Features

True Left-Handed Ejection Port: Features a dedicated mirrored upper receiver configuration that directs hot gas residue and shell debris away from left-handed eyes, solving the primary downside of right-handed tactical conversions.
Integrated Linear Flash Can: Outfitted with a premium muzzle blast diverter that gathers expanding gases and channels the horizontal sound signature and muzzle flash straight down the firing line.
Maneuverable 14.5-Inch Profile: The highly versatile 14.5" barrel profile maximizes portability and quick weapon manipulation, serving as an ideal platform for a lightweight pistol or registered short-barreled rifle build.
Optimized Mid-Length Gas Dwell: Tuned with a mid-length gas system to stabilize internal carrier pressures, which smooths out component integration, extends parts lifespan, and creates a soft recoil impulse.
Melonite/Nitride Bore Finish: The heavy-duty 4150 CMV steel barrel undergoes an advanced Salt Bath Melonite process inside and out. This high-grade treatment increases surface slickness, shrugs off moisture, and fights off gas port erosion.
Extended Free-Float M-LOK Handguard: Machined from lightweight 6061-T6 aluminum, the extended rail wraps cleanly around the linear flash can for a streamlined aesthetic while maximizing modular accessory attachment space.

Why Choose This Product?

The PRO2A Left Hand 14.5" 5.56 NATO Mid Length Upper with Flash Can offers a complete solution for left-handed shooters building a nimble, responsive defensive rifle or pistol platform. Standard right-handed short barrels release significant muzzle concussion sideways while venting harsh debris directly backward into a left-handed shooter's face. This setup solves both issues simultaneously by utilizing a true mirrored left-handed receiver layout and a linear flash can that safely directs muzzle pressure downrange.

Choosing a 14.5-inch barrel paired with a mid-length gas system also provides exceptionally soft cycling behavior. This combination avoids the high bolt speeds common in carbine gas systems while maintaining a short, nimble front profile. The extended M-LOK handguard covers the flash can to ensure maximum support-hand rail space for lights, lasers, and tape switches. Backed completely by Pro2A Tactical's signature Lifetime Factory Warranty and built with 100% American craftsmanship, this upper delivers dedicated ergonomics and dependable reliability out of the box.
