PRO2A LEFT HAND 22" 223 Wylde 1/7 Rifle Length Stainless Premium NR Side Charging M-LOK AR-15 Upper

Elite Match-Grade Varmint Precision Engineered for the Southpaw Marksman

Squeeze every ounce of velocity and mechanical accuracy out of your small-frame precision layout without standard right-hand limitations. The PRO2A Left Hand 22" 223 Wylde Rifle-Length Non-Reciprocating (NR) Side Charging Premium Stainless Upper Assembly completely modernizes the manual of arms for left-handed shooters. By combining a mirrored left-eject port layout with an ergonomic left-side charging handle, this upper keeps hot brass and escaping gases completely out of your peripheral line of sight. The non-reciprocating cocking handle stays fully stationary during cycling, preventing it from striking bulky target optics or gear. Built around an extended 22-inch premium 416R stainless steel barrel chambered in the versatile .223 Wylde, this upper drops natively onto any Mil-Spec lower receiver to anchor a flat-shooting, ultra-precise rifle build. Proudly 100% designed, machined, and meticulously hand-assembled in the USA.

Key Features

  • Mirrored Left-Hand Port & Side Charging Layout: Specifically designed to safely redirect spent casings and concentrated powder blowback out of the left side. The stationary side lever lets you charge the system easily from a prone or benched shooting position, maintaining constant weapon alignment.
  • Match-Grade 416R Stainless Steel Barrel: Crafted from elite 416R stainless steel, this 22-inch heavy profile barrel delivers ultimate structural resistance against rapid thermal growth and aggressive friction, yielding predictable shot groupings and exceptional point-of-impact consistency at long ranges.
  • Precision .223 Wylde Chambering: Specially engineered with the tighter throat tolerances of a .223 Wylde chamber. It safely fires both high-pressure military-surplus 5.56x45mm NATO and commercial .223 Remington ammunition with significantly enhanced downrange accuracy over traditional 5.56 chambers.
  • Extended 22-Inch Barrel Velocity: The extra barrel length significantly extends the expansion time of burning powder gases, yielding the highest possible muzzle velocities for the cartridge to secure a flatter trajectory and less wind drift at extreme distances.
  • Smooth Rifle-Length Gas Dwell: Tuning an extended 22-inch barrel with a true rifle-length gas tube lowers port pressure and slows the bolt carrier cycle. The results are an exceptionally soft recoil pulse, reduced parts fatigue, and effortless sight-picture tracking.

Who Chooses This Upper Receiver?

Southpaw Benchrest & F-Class Competitors

Left-handed marksmen who require extreme accuracy trust the mechanical consistency of a 416R stainless barrel and .223 Wylde chamber to consistently keep group sizes minimal during tight precision strings at extended ranges.

Southpaw Varmint & Open-Country Hunters

Shooters wanting to stretch the field distances of small varmints or coyotes rely on the full 22-inch configuration to gain maximum velocity. The mirror-ejection layout ensures that quick follow-up shots are taken without hot brass or heavy smoke getting blown into the shooter's eyes.

Oversized, Thermal & Night Vision Users

Hunters running large scopes, heavy night-vision arrays, or thermal sights prefer side-charging platforms. The left-side charging handle clears the bulky undersides of target optical bases, keeping knuckles completely safe from scraping against heavy mounts.
