The PRO2A Left Hand 5" 5.56 NATO Micro Length Melonite M-LOK Upper Kit with Flash Can offers an ultra-compact, personal defense weapon (PDW) construction package engineered specifically for left-handed operators. To master the extreme ballistic and concussive hurdles inherent to ultra-short 5.56 platforms, this micro configuration features an aggressive 1/5 twist rate to maximize projectile stabilization and prevent keyholing. Paired with a recessed linear blast-forwarding Flash Can that routes high-pressure gases downrange and away from the operator's support hand, this all-in-one completion package bundles a true left-ejecting forged receiver, dedicated left-handed bolt carrier group, full lower parts completion set, and an adjustable stock assembly to streamline your stripped lower receiver into an elite micro platform.
