The PRO2A LEFT HAND 6" 300 Blackout 1/7 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can maximizes short-barreled efficiency, blast mitigation, and shooter safety into a premium micro-sized tactical layout. Chambered for versatile use with the .300 AAC Blackout cartridge, this true left-handed assembly utilizes a mirror-image left side ejection port to push expanding gas blowback and spent brass safely clear of southpaw eyes. It discards the standard rear charging handle for an ergonomic, Non-Reciprocating (NR) left-side charging interface. To tame the extreme muzzle blast and sound pressure inherent to micro configurations, this model incorporates an integrated project-forward Flash Can muzzle device tucked cleanly beneath the handguard.

Running a heavy cartridge like the 300 Blackout through an ultra-short 6-inch barrel typically creates a punishing concussive signature and noticeable muzzle flash. For a left-handed shooter on a standard right-hand upper, this means breathing in heavy exhaust gas while dodging spent shells. The PRO2A Left-Hand Side Charging Flash Can Upper elegantly addresses every single one of these operational hurdles. By combining a dedicated left-ejecting chassis with a project-forward linear flash can, noise and hot debris are pushed completely away from your eyes and ears.Choosing a 6-inch barrel length hits the absolute peak configuration for a Personal Defense Weapon (PDW), maximizing portability without sacrificing complete powder burn or downrange kinetic energy—as the 300 BLK is uniquely engineered to thrive out of short envelopes. Complete with a fluid, stationary side charging handle that allows fast manipulation without breaking your optic alignment, this assembly offers southpaw operators a smooth-cycling, ultra-compact powerhouse built to perform under pressure.
