Cameron from Palmetto State Armory showcases the new H&R 300 Blackout Commando, a highly requested follow-up to last year’s 733 model in 5.56. This version features a 10.5” 1:8 twist barrel, rifle-height front sight, and a Kino-style gas system with the gas block tucked beneath the handguard. It’s built on a C7 upper receiver paired with a mil-spec lower, complete with a mil-spec trigger and six-position buffer tube.
Shipped with an H&R brace, A2 grip, and PMAG, the Commando is available as a complete pistol or as a standalone upper. Cameron puts it through its paces with a suppressor and red dot optic setup, running both subsonic and supersonic ammo flawlessly.
