Optimize your compact tactical footprint while maintaining absolute ergonomic safety. The PRO2A LEFT HAND 10.5" 300 Blackout Upper Kit with Flash Can delivers a tailored, high-performance configuration engineered natively from the ground up for left-handed operators. Utilizing a mirrored left-ejecting receiver profile and a matching left-hand M16 bolt carrier group, this complete package routes hot gases and spent casings safely down the left side, keeping your line of sight completely clear. The 10.5-inch medium profile barrel extracts excellent velocity and muzzle energy parameters from the versatile 300 Blackout round, while the recessed slimline flash can drives hard muzzle blast and concussion vectors directly downrange. Combined with an all-inclusive lower receiver conversion kit, this package simplifies your entire custom build project.

The 10.5-inch barrel configuration provides the ideal balance of complete powder combustion and velocity extraction for the 300 Blackout cartridge, but running standard right-handed short uppers sends concussive blast right toward a southpaw shooter's face. Pro2A Tactical eliminates this hazard entirely. By matching true left-handed mechanics with an extended 12-inch handguard and forward-directing flash can setup, this complete, American-made kit yields a safe, stable, and highly capable defensive platform.
