PRO2A 10.5" 350 Legend 1/16 Pistol Length Melonite M-LOK AR-15 Upper with Flash Can
Product Overview
The PRO2A 10.5" 350 Legend Barreled Upper Receiver with Flash Can brings optimized straight-wall cartridge performance into a highly refined, compact package. Outfitted with a specialized muzzle-mounted slimline flash can, this configuration redirects concussive blast and acoustic resonance directly away from the shooter. Designed as a drop-in replacement upper, it features a premium liquid-nitrocarburized barrel with an engineered single-large ramp system to ensure reliable extraction with straight-walled case configurations.
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.
- Straight-Wall Compliance: Specifically optimized for the 350 Legend cartridge, making it an excellent compact choice for states or zones with restrictive straight-wall firearm hunting mandates.
- 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?

By integrating an advanced linear flash can directly inside a longer M-LOK handguard profile, Pro2A Tactical delivers an incredibly streamlined look that significantly increases shooting comfort. Combined with a complete build assembly, this kit removes the guesswork from building a premium, legal-compliant hunting or defense pistol.
