Rifle. Not firearm. Otherwise every pistol that isn't a muzzle/breech loader or revolver is an 'assault weapon', which is makes the distinction even more functionally useless.
Maybe not legally in any part of the US unless Glock sells models with threaded barrels (vs. their factory aftermarket ones), but I don't doubt rhetorically.
In the most dire situation they're a tool in a crisis to allow you to get to your long gun.
More generally, "assault weapon" a long time ago meant things like track mounted artillery designed for offensive roles, and as noted by others was more recently coined and defined by US gun grabbers as a purely political term.
