An Austin gun shop proprietor succeeded Friday on a times-long hunt to capsize a civil ban on bump stocks, winning a 6- 3 palm from theU.S. Supreme Court. Bump stocks are bias that allowsemi-automatic rifles to fire hundreds of rounds in a nanosecond. The court ruled the civil Bureau of Alcohol, Tobacco, Arms and Snares can't include bump stocks under legislation banning machine ordnance. The capsized ATF rule needed possessors of bump stocks to either destroy them or surrender them to the ATF to avoid felonious execution. The case was filed by Michael Cargill, the proprietor of Central Texas Gun Works and an open exponent of gun rights in Texas, after he surrendered two bump stocks to the ATF. He argued that ATF inaptly linked bump stocks as machine ordnance, and surpassed its power in banning them. He brought the case with the support of the advocacy group the New Civil Liberties Alliance. The nearly 100- time-old law banning machine ordnance defines the armament as “ any armament which shoots, is designed to shoot, or can be readily restored to shoot, automatically further than one shot, without homemade reloading, by a single function of the detector. ” The ATF began including bump stocks under the description of “ machinegun ” during the Trump administration in response to the deadly mass firing on the Las Vegas Strip in 2017.
