Abstract
The invention concerns a marking for the barrel of a firearm, in particular of a pistol, a rifle, or a carbine, with a barrel cross section the perimeter of which alternately consists of linear, polygonal segments and arched segments, where necessary with transitions between them, whereby the linear, polygonal segments define an inscribed circle, further comprising at least two ribs being provided in or on the arched segments which extend radially inward.
Claims7
A polygonal barrel of a firearm, comprising:
- a barrel having a cross-sectional profile that corresponds to a rounded regular polygon defined by alternating linear and arched segments, each segment transitioning smoothly into its adjacent segments, the innermost point of each linear segment disposed upon and defining an inscribed circle;
- wherein the barrel further includes at least two inwardly extending ribs having profiles that are distinct from and superimposed upon the profile of the rounded regular polygon, each rib extending radially inward from an arched segment of the rounded regular polygon but extending no farther than the inscribed circle.
