Abstract:
A firearm barrel has an elongated body defining a bore and defining a bore axis, the body defining a breech end and an opposed muzzle end, a chamber defined in the breech end and contiguous with the bore; the bore having an interior surface having a plurality of alternating lands and grooves, the grooves being surfaces separated from the bore axis by first radius, the lands being surfaces separated from the bore axis by second radius less than the first radius and the lands and grooves being straight elements parallel to the bore axis, such that no spin is imparted to a projectile propelled down the bore. The lands and grooves may extend from the chamber to the muzzle end. The bore may have a constant cross-sectional profile along its length.

Claim (Index 1):
A firearm barrel comprising:\n an elongated body defining a bore and defining a bore axis; the body defining a breech end and an opposed muzzle end; a chamber defined in the breech end and contiguous with the bore; wherein the chamber is sized to receive a centerfire cartridge; the bore having an interior surface having a plurality of alternating lands and grooves; the grooves being surfaces separated from the bore axis by first radius; the lands being surfaces separated from the bore axis by second radius less than the first radius; and the lands and grooves being straight elements parallel to the bore axis, such that no spin is imparted to a projectile propelled down the bore.
