The ATF’s intention to redefine the term “machinegun” was published in the Federal Register on December 26, 2017. The agency is accepting public comments on their plans for backdoor gun control from now until late January.
Their announcement says, “Written comments must be postmarked and electronic comments must be submitted on or before January 25, 2018. Commenters should be aware that the electronic Federal Docket Management System will not accept comments after Midnight Eastern Standard Time on the last day of the comment period.”
The ATF/DOJ push for redefining the term “machinegun” would essentially eliminate any difference between accessories and conversion devices, treating both categories as a means of converting semiautomatics into full autos. This, in turn, would bring bump stocks under the auspices of the National Firearms Act (1934), requiring that the accessories be registered with the government and that owners of bump stocks be fingerprinted, photographed, and required to undergo a background check.
