The ATF’s politically-motivated redefinition of a bump stock as a machinegun was published today in the Federal Register as Docket No. 2018R–22F; AG Order No. 4367–2018. It becomes effective ninety days later, on Wednesday, March 26, 2019.
Anyone owning a bump stock must either destroy or surrender (without just compensation) their bump stock lest they face a punishment of 10 years imprisonment and/or a $250,000 fine.
