Oh!!! I get it now. It was a rhetorical question. My bad. I sincerely thought you sounded like all the people asking why anyone needs an AR15. You know, like, ‘why do you need an AR 15? I don’t see why anyone needs an AR assault rifle.’ I must have completely misread that.My comment was in regards to the unnecessary length and weight of a pistol caliber carbine when there are a ton of options in a pistol caliber *pistol.* It didn’t really have anything to do with the purpose of the gun. Pistol caliber ammunition is typically designed around short barrels and even bunny fart 9mm can reach out to 100 yards. For fun factor, suppressing it makes sense. Suppressing a 16* carbine makes for a long firearm. So that again brings us back to pistol caliber pistols.
Most people I know with PCC’s either use them for competition or bought them before adjustable braces existed.
