PRO2A 10.5" 350 Legend 1/16 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can
Product Overview
The PRO2A 10.5" 350 Legend Pistol Length Barreled Upper Receiver with Flash Can delivers smooth modern ergonomics and hard-hitting tactical ballistics in an optimized footprint. Engineered around a premium Gibbz Arms G4 Non-Reciprocating (NR) side-charging billet receiver, this system completely removes the traditional rear charging constraint to enable fast manual cycling that stays independent of your optics layout. Equipped with a muzzle-mounted slimline linear flash can tucked under an extended handguard, it routes concussive blast and audio resonance directly downrange away from the operator.
Key Features
- Ultra-Compact Profile: 10.5-inch heavy target barrel configuration delivers massive close-range kinetic energy transfer from a highly maneuverable, lightweight footprint.
- Non-Reciprocating Side Charging Mechanics: Advanced side-charging handle design remains completely stationary during cyclic firing, eliminating moving external interferences and optimizing clearance for low-mounted optics and thermal scopes.
- QPQ Melonite Extreme Armor: Barrel bore, chamber, and exterior are fully liquid nitrocarburized to exceed mil-spec chrome lining in surface hardness, heat dissipation, and corrosion resistance.
- Slim Profile M-LOK Workspace: Features a continuous top Picatinny rail interface seamlessly blended into a 12-inch free-floating M-LOK handguard for rigid optics and accessory mounting stability.

Why Choose This Product?
Short-barreled straight-wall platforms are notorious for generating aggressive side concussion and optical blockages from traditional charging profiles. Pro2A Tactical solves both issues simultaneously by utilizing a tucked linear flash can that isolates lateral muzzle blast, combined with a static, Gen 2 left-side manual handle structure. This configuration delivers an incredibly streamlined look that maximizes scope clearance and driving comfort, offering straight-wall hunters an uncompromised tactical foundation.
