The Definition of Parabellum

Usually referred to as a Kentucky Long Rifle or simply Longrifle, the Kentucky Rifle is a flintlock rifle with a long barrel and short, crooked stock. It is widely believed to be a largely unique development of American rifles that was uncommon in European rifles of the same period.

or in the case of shotshells, for a specific weight of shot and wad column.
American name for the German "Parabellum" semiautomatic pistol introduced in 1900.
The Parabellum was designed by Georg Luger, and based on the earlier Borchardt pistol.

A screw with about half of its threading removed in longitudinal sections. Often used at the breech end of a
takedown firearm's barrel. When the barrel's interrupted female threads are inserted into the receiver's
