I've been thinking of adding a 300 Blackout barrel for my AR (5.56/16"/mid-length gas tube), but I do not find any barrels set up for mid-length. They're all pistol or carbine length. I assume that has something to do with available gas pressure? So, if there's no such thing as a mid-length 300 Blackout barrel, which one would you go with ... pistol or carbine? I might someday add a suppressor, but not in the near future. Thanks!
