PRO2A LEFT HAND 16" 5.56 NATO 1/7 Melonite M-LOK AR-15 Upper with Flash Can
Product Overview
The PRO2A Left Hand 16" 5.56 NATO Barreled Upper Receiver with Flash Can delivers elite uncompromised ergonomics for the southpaw operator. Purpose-built around a dedicated left-ejecting receiver housing, this upper safely routes gases and spent casings away from the shooter's line of sight. It features a premium, liquid-nitrocarburized 1:7 twist barrel optimized for heavy grain projectiles, capped off with a muzzle-mounted slimline linear flash can. Safely nested inside an extended free-float handguard, the flash can redirects concussive resonance straight downrange for a vastly improved shooting experience.
Key Features
- Dedicated Left-Hand Architecture: Engineered exclusively for southpaw shooters, utilizing a true left-ejecting receiver housing that isolates face-adjacent gas blowback and hot brass deflection.
- Ultra-Compact Profile: 16-inch heavy target barrel configuration delivers massive close-range kinetic energy transfer from a highly maneuverable, lightweight footprint.
- Versatile Twist Optimization: Precision 1:16 twist profile natively stabilizes a vast spectrum of cartridge architectures from light practice loads to heavy duty straight-wall hunting configurations.
- 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 an extended free-floating M-LOK handguard for rigid optics and accessory mounting stability.

Why Choose This Product?
Left-handed shooters operating standard right-side eject platforms consistently deal with facial unburnt powder sprays and harsh gas drift. Pro2A Tactical removes this compromise completely by building an authentic left-ejecting setup around an exceptionally durable Mid-length gas system. Paired with a tucked linear flash can that isolates lateral muzzle pop, it grants southpaw operators a smooth-cycling, clean-running, and incredibly rugged 5.56 baseline upper assembly.
