PRO2A LEFT HAND 12.5" 6.5 Grendel 1/8 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper Kit

Product Overview

The PRO2A LEFT HAND 12.5" 6.5 Grendel 1/8 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper Kit balances mid-to-long-range ballistic dominance with optimized southpaw ergonomics in a highly agile footprint. Built around a precision 12.5-inch 4150 CMV steel barrel chambered for Type II 6.5 Grendel, this complete conversion package transitions a standard frame into a flat-shooting, high-energy tactical build. Engineered with a premium mirrored left-ejecting Non-Reciprocating (NR) side-charging handle, this system gives left-dominant shooters smooth manual control without standard rear charging disruptions or facial debris blowback. This range-ready conversion package includes the left-handed bolt carrier group, full lower parts tree, and buffer tube assembly equipment.

Key Features

  • True Left-Handed Ejection Layout: Mirrored upper receiver design safely throws spent Type II brass casings and concussive cylinder gas to the left, away from the operator's face and eyes.
  • Non-Reciprocating Right Side Charging: The ergonomic manual charging handle remains completely stationary during firing sequences, preventing thumb interference and maintaining clear sight lines below mounted optics.
  • Heavy-Duty Melonite Barrel Defense: Liquid QPQ Nitride treatment maximizes land-and-groove core micro-hardness, defending against thermal throat erosion and outdoor environmental elements.
  • Tuned Carbine-Length Gas Configuration: Smoothly regulates internal block pressures to optimize cycling extraction dwelling times and mitigate physical muzzle climb in a compact barrel profile.
  • All-In-One Conversion Bundle: Arrives completely configured with a left-handed 6.5 Grendel Bolt Carrier Group (BCG), free-float slim M-LOK handguard, complete lower parts kit matrix, and buffer tube hardware gear.
