PRO2A 10.5" 7.62x39 1/10 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper
Product Overview
The PRO2A 10.5" 7.62x39 Carbine Length Barreled Upper Receiver pairs smooth, modern ergonomics with hard-hitting ballistic performance. Engineered around a premium Gibbz Arms G4 Non-Reciprocating (NR) side-charging billet receiver, this platform completely removes the traditional rear charging handle constraint to deliver fast manual cycling that won't interfere with large optics. Built as a high-performance drop-in upper, it features a heavy-profile Melonite barrel utilizing a carbine-length direct impingement gas system explicitly engineered to yield smoother cycling pressures and long-term reliability.
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 9-inch free-floating M-LOK handguard for rigid optics and accessory mounting stability.

Why Choose This Product?
Building a 7.62x39 platform with a traditional charging layout often limits your workspace when running bulky optics. Pro2A Tactical solves this explicitly by integrating a static, non-reciprocating side handle onto a billet upper assembly. Combined with a carbine-length gas system, it softens the sharp bolt velocity inherent to the caliber, delivering a reliable, flat-shooting foundation for your tactical or hunting requirements.
