The Definition of Polygonal Rifling
A type of gun barrel rifling where the traditional lands and grooves are replaced by "hills and valleys" in a rounded polygonal pattern, usually a hexagon or octagon.
Polygons with a larger number of edges provide a better gas seal in relatively large diameter polygonally rifled bores.
