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.

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.
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.
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.
