PRO2A LEFT HAND 22" 224 Valkyrie 1/6.5 Rifle Length Melonite M-LOK AR-15 Upper Kit

Extreme Long-Range Accuracy and Southpaw Ergonomics in an All-In-One Build Package

Push the boundaries of the MSR platform past the 1,000-yard milestone without battling face-directed gas or casing deflection. The PRO2A Left Hand 22" 224 Valkyrie Rifle-Length Melonite AR-15 Upper Kit is a master-tier, comprehensive assembly package combining a precision left-ejecting upper assembly, matching left-hand bolt carrier group (BCG), charging handle, lower parts kit, and adjustable stock setup. Built around an extended 22-inch 4150 CMV steel barrel with an ultra-fast 1:6.5 twist rate, this configuration provides the high rotational velocity necessary to stabilize heavy, low-drag long-range projectiles. The rifle-length gas system balances high pressure safely, generating exceptionally flat trajectories and minimum recoil. Designed to drop flawlessly onto your preferred standard stripped lower receiver, this complete package introduces true ergonomic equity to long-range tactical shooters. Proudly 100% designed, machined, and precision-tested in the USA.

Key Features

  • Dedicated Left-Handed Ejection Port: Engineered with a mirrored billet receiver geometric profile that cleanly throws hot brass and unburnt powder gases to the left side, keeping the operator's line of sight perfectly clear.
  • All-In-One Complete Rifle Build Package: Takes the technical guesswork out of building a long-range setup. This comprehensive kit arrives with a matching left-hand bolt carrier group, standard grip, polished trigger assembly, and lower component springs—everything needed to finish a stripped lower.
  • Ultra-Fast 1:6.5 Twist Rate: Precision button-rifled with an aggressive 1:6.5 twist configuration engineered specifically to stabilize heavy, high-BC long-range bullets (such as 80gr, 88gr, and 90gr options) over extended distances.
  • Maximized 22-Inch Velocity & Melonite Finish: The extended 22-inch barrel provides full powder combustion for maximum muzzle velocity, while the Salt Bath Melonite finish inside and out protects against throat erosion and moisture.
  • Ultra-Smooth Rifle-Length Gas Dwell: Pairing an extended barrel with a true rifle-length gas tube tames high internal velocities, establishing an exceptionally soft recoil impulse that limits benchrest scope disruption.
  • Slim Profile Free-Float M-LOK Handguard: Crafted from premium 6061-T6 aluminum, the free-float rail isolates barrel vibrations to preserve uniform accuracy while offering massive M-LOK modular real estate.

Why Choose This Product?

The PRO2A Left Hand 22" 224 Valkyrie Master Build Kit completely eliminates the operational struggles left-handed shooters experience during precision benchrest or long-range prone strings. Standard right-handed receivers vent heavy pressure spikes and powder debris directly across a left-dominant shooter's face, causing severe eye distraction and fatigue during match sequences. Flipping the ejection path permanently resolves this issue, ensuring full safety and comfort.
