PRO2A LEFT HAND 18" 350 Legend 1/16 Carbine Length Melonite M-LOK AR-15 Upper Kit

Product Description

Squeeze every ounce of downrange performance and velocity out of the straight-walled cartridge with the PRO2A LEFT HAND 18" 350 Legend Upper Kit. Purpose-built from the ground up for left-handed operators, this rifle kit completely eliminates the traditional frustration of cross-body brass throwing and facial gas blowback via its mirrored left-ejecting system. The elongated 18-inch medium profile barrel delivers maximum powder burn efficiency and superior muzzle velocity, ensuring peak accuracy at extended distances. Bundled with a premium 15-inch free-float M-LOK rail and all the lower completion components, this all-in-one package turns your stripped lower receiver into an elite southpaw hunting machine.

Key Features

  • Elongated 18-Inch Velocity: Optimizes straight-walled hunting terminal performance by maximizing velocity retention and flattening standard trajectories.
  • Dedicated Southpaw Cycling: True mirrored left-ejection ensures all gases and mechanical blowback vent safely away from left-handed operators.
  • Melonite Surface Enhancement: Premium 4150 Chrome Moly Vanadium steel barrel treated with liquid QPQ nitride to withstand severe backwoods weather and extreme heat.
  • Rigid M-LOK Handguard: The 15-inch slim free-floating aluminum rail ensures excellent ergonomics and solid mounting real estate for optics, bipods, and accessories.
  • Comprehensive Lower Assembly Integration: Ships with an all-inclusive lower parts kit and defensive stock group to simplify your custom build process.
