PRO2A Left Hand 18" 6.5 Grendel NR Side Charging Melonite M-LOK Upper Kit
PRO2A LEFT HAND 18" 6.5 Grendel 1/8 Mid Length NR Side Charging Melonite M-LOK AR-15 Upper Kit
Product Overview
The PRO2A LEFT HAND 18" 6.5 Grendel 1/8 Mid Length NR Side Charging Melonite M-LOK AR-15 Upper Kit brings maximized velocity, elite long-range ballistic potential, and optimized ergonomics to left-handed marksmen. Chambered in the inherently flat-shooting 6.5 Grendel cartridge, this performance upper kit completamente reinvents the cycle process with a **Non-Reciprocating (NR) side-charging handle** paired with a true left-hand ejection architecture. This configuration safely keeps high-pressure blowback gases and spent brass well away from left-dominant sightlines. Outfitted with an extended 18-inch premium Melonite-treated barrel for maximum terminal reach, a matching left-hand nitride bolt carrier group, a full lower parts kit, and an adjustable stock assembly, this kit contains all necessary components to convert your stripped lower receiver into a high-tier distance rifle.
Key Features
True Left-Handed Ejection Geometry: Purpose-built mirrored upper receiver architecture safely throws hot brass and unburnt powder to the left side, shielding the shooter's face from debris.
Non-Reciprocating Side Charging Handle: Right-side charging handle remains stationary while cycling, providing superior charging leverage under large optics without moving components interfering with your support hand.
Complete Left-Handed Drive Assembly: Ships with a dedicated true left-handed 6.5 Grendel Type II bolt carrier group for seamless lockup, smooth extraction, and high-tier ignition reliability.
All-In-One Lower Completion Bundle: Includes a premium complete Mil-Spec lower parts kit and a standard six-position adjustable carbine stock setup for an effortless unified build experience.
Velocity-Optimized 18" Barrel: Extended barrel profile maximizes powder burn efficiency for the 6.5 Grendel cartridge, yielding flatter trajectories and tighter groupings at extreme distances.
Rugged QPQ Melonite Armour: Liquid nitride treatment hardens internal bore components to maximize barrel lifespan, ensure low-friction cleaning, and guard against environmental elements.

Why Choose This Product?
For left-handed shooters pushing the maximum distance boundaries of the 6.5 Grendel cartridge, standard right-handed rear-charging rifles introduce substantial layout drawbacks—including face-level carbon blowback, poor manual extraction clearance beneath large long-range scopes, and erratic casing pathways. This PRO2A kit addresses these hurdles at their mechanical root by shifting structural components into a true left-side ejection architecture combined with an ergonomic, static side-charging mechanism. This allows you to smoothly cycle the action without breaking your cheek weld or losing target focus. Bundled with fully matched lower completion internals, it provides southpaw long-range marksmen a faster, safer, and heavily streamlined build project.
