PRO2A LEFT HAND 7.5" 350 Legend 1/16 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can

Product Description

Maximize close-range maneuverability, straight-wall firepower, and complete ergonomic optimization with the premium PRO2A LEFT HAND 7.5" 350 Legend Pistol Length Non-Reciprocating (NR) Side Charging Assembled Upper Receiver with Flash Can. Explicitly configured as a standalone compact barreled upper assembly, this unit features an ultra-short 7.5-inch precision barrel engineered to satisfy heavy impact requirements from a highly portable footprint. To combat the severe muzzle blast and noise signature typical of micro straight-wall configurations, an integrated slimline linear flash can is installed to capture expanding gases and redirect concussive force safely downrange away from the operator. The architecture centers around a dedicated left-ejecting Gibbz Arms G4 billet receiver layout, providing unhindered manual left-side lever manipulation while completely eliminating right-side gas blowback, chemical smells, and hot casing debris from tracking across a left-handed shooter's line of sight.

Key Features

True Left-Hand Architecture: Configured with a dedicated left-side ejection port orientation to safely route spent casing paths and high-pressure expansion gases away from southpaw operators.
Non-Reciprocating Side Charger: Premium patent-pending Gibbz Arms G4 billet receiver architecture ensures the side-charging handle remains completely stationary while firing to maintain unobstructed visual clearance under oversized optics, red dots, or thermal scopes.
Forward-Directed Flash Can: Slimline linear muzzle flash can captures aggressive short-barrel expansion blast, driving the acoustic reporting forward to maximize shooter comfort.
Ultra-Compact Micro Footprint: A premium 7.5-inch heavy-duty barrel profile offers an exceptionally small maneuverability profile ideal for personal defense weapon (PDW) builds, truck carry, or tight hunting blinds.
Straight-Wall Performance: Specifically optimized for the 350 Legend cartridge, granting heavy downrange energy transfer from a compact modern sporting platform configuration.
Precision 1:16 Twist Rate: Perfectly tailored twist dynamic stabilizes standard and high-grain commercial ammunition options to maintain solid terminal ballistics.
QPQ Melonite Hardened Protection: Inside barrel bore, chamber throat, and exterior walls are fully liquid nitrocarburized to maximize surface hardness, improve thermal dissipation boundaries, and resist extreme environmental degradation.
Recessed Free-Float Workspace: A continuous top Picatinny rail aligns flawlessly with a 9-inch ultra-lightweight free-floating M-LOK handguard that beautifully shrouds and recesses the flash can muzzle profile for a clean, integrated look.

Why Choose This Product?

The PRO2A Left-Hand 7.5" 350 Legend Non-Reciprocating Side Charging Upper Receiver with Flash Can offers custom southpaw builders an exceptional, micro-sized baseline without forcing the purchase of redundant internal bolt carrier elements or standard lower stock kits they may already have on hand. Sourcing standalone components for unique left-handed calibers often creates headspacing risks or feeding failures with straight-walled cases. This system resolves that constraint out of the box, utilizing a mirrored left-hand single large M4 feed ramp configuration built explicitly to chamber straight-wall ammunition smoothly. Traditional rear-charging upper units create awkward physical manipulation clearances and force left-handed operators to breathe in exhausting chemical blowback gases. Utilizing the mirrored forge design and premium Gibbz Arms G4 side-charging framework resolves this obstacle entirely, allowing clean manual charging execution while keeping your cheek weld firmly established. Complemented by an extended 9-inch free-floating rail that beautifully envelopes the blast-directing linear flash can, it delivers a flat-shooting, modern tuck-style profile engineered for extreme operational environments under the total protection of an unconditional Structural Lifetime Warranty.
