Abstract
A firearm component including a barrel having a bore extending to a generally circular aperture at a forward end of the barrel. The barrel has a series of compensator slots spaced at equal intervals along the bore. Each slot has an oblong cross section extending through the barrel from an interior surface to an exterior surface having a major axis and a minor axis. The cross section also has a length measured along the major axis and a width measured along the minor axis that is shorter than the length. The interval between each adjacent pair of slots in said series of compensator slots has a width greater than the width of each slot in the adjacent pair. At least a portion of the cross section extends below the central bore axis.
Claims43
A firearm component, comprising an elongate barrel having a generally cylindrical interior surface defining a bore extending along a central bore axis to a generally circular aperture at a forward end of the barrel through which a projectile is shot when the firearm is fired, said bore and aperture sharing a common bore diameter, the interior surface having a helical rifling groove extending along the interior surface around the central bore axis, said barrel having a series of compensator slots spaced at equal intervals along the bore, each compensator slot in said series of compensator slots having an oblong cross section extending through the barrel from the interior surface to an exterior surface of the barrel allowing gases to travel through said slot from the bore when the firearm is fired, the cross section having:
- a major axis extending transverse to the central bore axis;
- a minor axis extending transverse to the major axis and parallel to the central bore axis;
- a length measured along the major axis at the interior surface of the barrel;
- and
- a width measured along the minor axis at the interior surface of the barrel that is shorter than the length, and wherein:
- the interval between each adjacent pair of slots in said series of compensator slots has a width at the interior surface of the barrel greater than the width of each slot in said adjacent pair of slots;
- the helical rifling groove extends to the aperture;
- and
- at least a portion of the cross section extends below the central bore axis.
A firearm component as recited in claim 22, wherein:
- the series of compensator slots consists of an equal number of slots as the series of barrel grooves has barrel grooves;
- and
- each barrel groove in the series of barrel grooves axially overlaps a corresponding slot of said series of compensator slots.
A firearm component, comprising an elongate barrel having a generally cylindrical interior surface defining a bore extending along a central bore axis to a generally circular aperture at a forward end of the barrel through which a projectile is shot when the firearm is fired, said bore and aperture sharing a common bore diameter, the interior surface having a helical rifling groove extending along the interior surface around the central bore axis to the aperture, said barrel having a first series of compensator slots spaced at intervals along the bore and a second series of compensator slots spaced at intervals along the bore, each slot in said second series of compensator slots being positioned on an opposite side of an imaginary plane that includes the central bore axis, each compensator slot in said first and second series of compensator slots having a racetrack-shaped cross section extending through the barrel from the interior surface to an exterior surface of the barrel allowing gases to travel through said slot from the bore when the firearm is fired, the cross section having:
- a major axis extending transverse to the central bore axis;
- a minor axis extending transverse to the major axis and parallel to the central bore axis;
- a length measured along the major axis at the interior surface of the barrel that is greater than about sixty percent of the bore diameter;
- and
- a width measured along the minor axis at the interior surface of the barrel that is less than about seventy percent of the bore diameter, the width being shorter than the length.
