you don't know a smoothbore from your asshole

WATCH THE VIDEOS AND BE AMAZED: they weren't fucking machine guns, they were propelled to those rates of fire with bumpstocks, you goddamn bellend. that's why prior service people like myself, who have been around machine guns IN REAL FUCKIN LIFE, understand there's no good reason for civilians to have them and devices like crank triggers and bumpstocks that approximate their rate of fire are fucking stupid and evil.
