PRO2A Left Hand 20" 6.5 Grendel NR Side Charging Melonite M-LOK Upper Kit
PRO2A LEFT HAND 20" 6.5 Grendel 1/8 Mid Length NR Side Charging Melonite M-LOK AR-15 Upper Kit
Product Overview
The PRO2A LEFT HAND 20" 6.5 Grendel 1/8 Mid Length NR Side Charging Melonite M-LOK AR-15 Upper Kit represents the absolute pinnacle of long-range performance and southpaw optimization for the AR-15 platform. Purpose-built around an extended, velocity-maximizing 20-inch Melonite barrel, this complete conversion kit extracts the maximum range, flattest trajectories, and ultimate ballistic energy inherent to the 6.5 Grendel cartridge. Featuring a premium **Left-Side Non-Reciprocating (NR) side-charging handle** and true left-handed ejection architecture, it isolates left-dominant marksmen from escaping gas blowout and hot spent brass pathway lines. Bundled completely with a matching left-hand nitride bolt carrier group, a full lower parts assembly, and a six-position adjustable stock kit, it features everything required to transform your stripped lower receiver into an elite, match-grade distance rifle configuration.
Key Features
True Left-Handed Ejection Geometry: Mirror-image port design ejects spent casings and hot carbon blast cleanly to the left, keeping your sightline unhindered and face protected.
Non-Reciprocating Side Charging Handle: Right-side side-charger remains completely stationary when firing, providing elite mechanical leverage under massive long-range optics without moving parts crossing support positions.
Matched Left-Hand Drive Group: Includes a dedicated true left-handed 6.5 Grendel Type II bolt carrier group (BCG) for seamless lockup, smooth high-pressure extractions, and reliable ignition.
Full Lower Completion Internals: Ships with a complete Mil-Spec lower parts kit (triggers, pins, springs, and grip) and a standard adjustable M4 carbine stock assembly with buffer assembly for an all-in-one build project.
Velocity-Maximizing 20" Barrel: Full 20-inch barrel profile delivers total powder burn efficiency, giving high-ballistic coefficient 6.5mm projectiles superior velocity retention beyond 800+ yards.
Ultra-Durable QPQ Melonite Armour: Premium Salt Bath Nitride treatment provides superior barrel bore hardness, corrosion defense, and effortless cleaning maintenance.

Why Choose This Product?
Left-handed marksmen building precision long-range rifles face serious layout compromises with standard right-handed rear-charging receivers—including face-level carbon blowback (highly magnified under gas-heavy supersonic rounds), poor manual clearing leverage beneath extended scopes, and unsafe casing pathways. This PRO2A kit overcomes these systemic design hurdles directly at the manufacturing level. By merging a full 20" velocity-retaining profile with a true left-side ejection architecture and a static side-charging sequence, you can cleanly cycle your action or manipulate the weapon system without ever leaving your cheek weld or losing target focus. Complete with premium matched lower completion internals, it gives southpaw precision riflemen a faster, safer, and heavily optimized long-distance platform build project.
