PRO2A LEFT HAND 10.5" 350 Legend 1/16 Pistol Length Melonite M-LOK AR-15 Upper Kit

Product Description

Maximize the ballistic potential of your straight-walled hunting setup with the PRO2A LEFT HAND 10.5" 350 Legend Upper Kit. Specifically designed for left-handed operators, this system eliminates the persistent issues of facial gas blowback and stray casings by utilizing a mirrored left-ejecting receiver profile. The 10.5-inch barrel offers a significant velocity boost over ultra-short pistol configurations, making it a stellar option for medium-game hunting or custom home-defense builds where maneuvering in tight spaces is paramount.

Key Features

  • Optimized 10.5-Inch Ballistics: Increased barrel length burns powder more efficiently, translating to flatter trajectories and harder impacts out to hunting distances.
  • Lefty-First Architecture: Mirrored port design protects southpaw operators from concussive facial blowback and cycling casings.
  • Melonite Enhanced Core: Premium QPQ Nitride treatment guarantees a resilient bore surface that resists heat friction and corrosive hunting elements.
  • Total Component Completeness: Avoid tracking down separate components—this all-inclusive package features everything necessary to complete your stripped lower receiver.
  • American Sourced & Built: Machined from high-grade aircraft-spec materials and assembled precisely in Georgia, USA.
