Draftfederal definition
For federal purposes, 26 U.S.C. section 5845(b) defines machinegun by automatic discharge of more than one shot, without manual reloading, through a single trigger function. [1] The definition also reaches specified frames or receivers, conversion components, and combinations of parts, so a completed firearm is not its only subject. [1] The Gun Control Act incorporates this NFA definition by reference. [2] The May 2026 tax rule identifies machineguns, together with destructive devices, as categories excluded from the new zero-dollar making and transfer rates. [3]
