Achieve optimal rifle ballistics and suppressed-like concussion management without traditional southpaw compromises. The PRO2A LEFT HAND 16" 300 Blackout Upper Kit with Flash Can offers a complete full-length build solution 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 package routes hot gases and spent casings safely down the left side, keeping your line of sight perfectly clear. Uniquely utilizing a pistol-length gas system on a full 16-inch barrel configuration, this setup yields maximum reliability when cycling heavy subsonic or lightweight supersonic projectiles. The recessed slimline flash can drives hard muzzle blast and concussion vectors directly downrange, while the 15-inch handguard provides a continuous gripping profile.

Most 16-inch 300 Blackout models utilize a carbine gas system, which can cause cycling hesitations with low-velocity subsonic loads. Pro2A Tactical remedies this by tuning a premium 16-inch barrel with a reliable pistol-length gas layout and a muzzle-directing flash can tucked inside a full 15-inch rail. Combined with an all-inclusive rifle-length stock bundle and true left-handed mechanical components, Pro2A Tactical removes the compromise from custom builds, ensuring southpaw shooters can step up to premium performance safely and comfortably.
