PRO2A Left Hand 16" 6.8 SPC II Melonite M-LOK AR-15 Upper Kit

PRO2A LEFT HAND 16" 6.8 SPC II 1/10 Mid Length Melonite M-LOK AR-15 Upper Kit

Product Description

Step up to premium medium-game hunting performance and heavy-hitting tactical capability with the PRO2A LEFT HAND 16" 6.8 SPC II Upper Kit. Engineered from the ground up natively for left-handed operators, this complete rifle package utilizes a mirrored left-ejecting receiver profile and dedicated left-hand M16 bolt carrier group. By routing gas pressure and spent casings safely away from your face, it removes the distractions traditional southpaws face. The 16-inch medium profile barrel optimizes the intermediate ballistics of the 6.8 SPC II round, while the mid-length gas system drops port pressures to guarantee exceptionally smooth, reliable cycling. This complete assembly kit features everything needed to finish a custom rifle build on your stripped lower receiver.

Key Features

True Left-Hand Architecture: Mirrored upper port arrangement completely eliminates cross-body brass throwing and concussive facial blowback.
Optimized Mid-Length Cycling: Smoother gas curve and lower internal pressures reduce mechanical wear while providing a soft-recoiling shooting experience.
High-Performance 6.8 SPC II Chambering: Specially optimized chamber setup provides superior reliability and velocity extraction with modern hunting and defense loads.
Premium QPQ Melonite Armor: Liquid nitride hardened 4150 Chrome Moly Vanadium barrel ensures extreme bore durability, corrosion resistance, and prolonged lifespan.
Complete Rifle Build Setup: Features a complete lower parts kit and standard rifle stock assembly—no piecemeal component sourcing required.
