PRO2A LEFT HAND 22" 6.5 Grendel 1/8 Rifle Length NR Side Charging Melonite M-LOK AR-15 Upper

Experience long-range big-bore performance optimized specifically for southpaw marksmen with the PRO2A Left Hand 22" 6.5 Grendel Non-Reciprocating (NR) Side Charging AR-15 Upper Receiver Group. This premium, 100% American-made assembly combines the flat-shooting, wind-defying ballistics of the 6.5 Grendel cartridge with an ergonomic left-handed setup. Shifting both the charging handle and the ejection port to align perfectly for left-side orientation, this upper prevents spent brass from crossing your line of sight. Built around an extra-long 22-inch Melonite barrel for maximized muzzle velocity and a smooth rifle-length gas system, it provides a stable, low-recoil precision foundation that drops directly onto any standard Mil-Spec AR-15 lower receiver.

Key Features

True Left-Hand Architecture: Explicitly engineered for southpaw shooters, utilizing a mirrored receiver layout with a left-side ejection port to throw hot brass clear of the user's face and vision.
Non-Reciprocating Side Charging Action: The ergonomic left-side charging system handle remains completely stationary while the rifle cycles, avoiding interference with large high-magnification optics and eliminating rear charging handle reach hurdles.
Extended 22" Melonite Protection: The premium 4150 CMV steel barrel is fully treated with an advanced Salt Bath Melonite finish inside the bore and across the exterior to optimize structural service life and maximize corrosion resistance.
Versatile 1:8 Twist Profile: Precision button-rifled twist rate optimized to effortlessly stabilize mid-to-heavy match projectiles, such as 123gr and 130gr loads, with exceptional long-range sub-MOA consistency.
Smooth Rifle-Length Gas Dynamics: Configured with a full rifle-length gas operating block to provide incredibly soft cycling pressures, reducing felt recoil and allowing swift follow-up tracking.
Slim Profile Free-Float M-LOK Handguard: Machined from high-strength aluminum, the lightweight rail isolates barrel vibrations to preserve uniform mechanical accuracy while providing modular M-LOK attachment slots.

Why Buy This Product?

Left-handed shooters looking to build a long-range 6.5 Grendel are usually forced to compromise, dealing with hot carbon and flying brass crossing their face from right-ejecting firearms. The PRO2A Left-Handed 22" 6.5 Grendel Non-Reciprocating Side Charging Upper solves this problem completely by mirroring the entire operating system. By marrying this left-eject architecture with a stationary side-cocking mechanism, you can fluidly cycle the weapon beneath large precision optics without moving your head or losing your sight line downrange. Hand-built, headspaced, and checked for absolute performance right here in the USA, this upper extracts the maximum potential velocity out of the 6.5 Grendel cartridge while giving southpaws the uncompromised shooting interface they deserve.
