Product Description

Upgrade your platform configuration with the premium PRO2A 7.5" 350 Legend Pistol-Length Non-Reciprocating (NR) Side Charging Assembled Upper Receiver. Engineered as a standalone micro barreled upper assembly, this unit features an ultra-short 7.5-inch precision straight-wall barrel engineered specifically to satisfy restricted hunting regulations or close-quarters defensive configurations while maintaining high kinetic delivery. The architecture centers around the world-renowned Gibbz Arms G4 billet receiver layout, providing unhindered manual left-side lever manipulation.

Key Features

• Non-Reciprocating Left-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 or high-profile red dots.
• 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 Dynamic Stability: Specifically optimized for the 350 Legend cartridge, granting massive downrange energy transfer from a highly compact modern sporting platform footprint.
• 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.
• Modular Free-Float Workspace: A continuous top Picatinny rail aligns flawlessly with a 7-inch lightweight slimline M-LOK handguard for secure accessory attachment without warping barrel zero.

Technical Specifications

Why Choose This Product?

The PRO2A 7.5" 350 Legend Non-Reciprocating Side Charging Upper Receiver provides an exceptional, high-tier baseline configuration without forcing you to purchase redundant internal bolt assemblies or standard mil-spec lower components you may already own. Sourcing standalone components for unique calibers often creates headspacing risk or feeding failure with straight-walled cases. This system resolves that obstacle entirely, utilizing a specialized single large M4 feed ramp configuration built explicitly to chamber straight-wall ammunition smoothly. Traditional rear-charging upper units create awkward physical manipulation clearances when running high-magnification optics or high-profile red dots. Incorporating the premium Gibbz Arms G4 side-charging framework resolves this obstacle entirely, allowing clean manual charging execution while keeping your cheek weld firmly established. Built in America to exacting manufacturing tolerances and guarded by an unconditional Structural Lifetime Warranty, it stands out as a highly reliable choice for shooters demanding customized mechanical durability from an agile platform.
