PRO2A LEFT HAND 10.5" 300 Blackout 1/7 or 1/5 Pistol Length Melonite AR-15 Upper Kit

Product Description

Maximize your terminal parameters and operational velocity with the PRO2A LEFT HAND 10.5" 300 Blackout Upper Kit. Specifically designed and tailored from the ground up for left-handed operators, this complete pistol bundle utilizes a mirrored left-ejecting receiver profile and matching left-hand M16 bolt carrier group. By redirecting spent brass and high-pressure gases down the left side, it entirely removes the facial gas blowback traditional southpaws suffer with right-handed setups. The 10.5-inch medium profile barrel delivers excellent velocity scaling for the intermediate 300 Blackout round, offered in 1:7 or 1:5 twist rates to accurately stabilize heavy subsonic match loads or standard supersonic defensive rounds. Paired with a free-float 9-inch M-LOK handguard and an all-inclusive lower conversion package, this turnkey kit streamlines your entire custom building project.

Key Features

• True Left-Hand Architecture: Dedicated mirrored left-ejection port setup protects left-handed operators from unmanaged gas blowback and hot cycling casings.
• Versatile Twist Rate Choice: Available in standard 1:7 or fast 1:5 twist options to reliably accommodate everything from lightweight supersonic defense rounds to heavy subsonic loads.
• Premium QPQ Melonite Protection: Liquid-nitride hardened 4150 Chrome Moly Vanadium steel barrel provides severe corrosion resistance and extended throat life.
• Slim Free-Float Handguard: Low-profile 9-inch aluminum M-LOK rail system ensures superior ergonomics and continuous mounting space for optics, lights, and tactical accessories.
• Turn-Key Completion Package: Arrives alongside a complete matching lower parts kit and high-density blade assembly to finish your custom stripped lower out of the box.
