Build a high-performance, ultra-compact host for your favorite silencer with the PRO2A LEFT HAND 6" 300 Blackout Suppressor Ready Upper Kit. Purpose-built for left-handed operators, this micro PDW package features a mirrored left-ejecting receiver profile and a matching left-hand M16 bolt carrier group. By routing gas pressure and spent casings safely down the left side, it solves the severe gas blowback that southpaws traditional suffer when running right-handed firearms suppressed. The 6-inch barrel is explicitly threaded and contoured for suppressor installation, while a standard 5-inch M-LOK handguard keeps the muzzle exposed for quick attachment mounting. This complete build kit arrives with all lower completion components to seamlessly turn your standard stripped lower into an elite quiet weapon system.

Running standard right-handed short-barreled uppers with a suppressor forces significant gas and debris directly back toward a left-handed shooter's face. Pro2A Tactical eliminates this hazard entirely. By matching true left-handed mechanics with a dedicated suppressor-ready barrel setup, this complete, American-made kit yields a safe, ultra-compact, and incredibly quiet defensive platform designed explicitly for southpaw requirements.
