Muzzle device
View Patent ↗The present invention is of a muzzle device that is either permanently fixed or releasably attached to the end of the barrel of a firearm. The muzzle device may have a configuration that reduces the loss of pressure and flow rate of the propellant gas by employing a central bore having approximately the same diameter as the bore of the barrel. The muzzle device may further have apertures with inserted adjustable screws with hollow interior portions for tuning the degree of propellant gases in various directions away from the muzzle device. The external diameter of the muzzle device may also have substantially the same diameter as the external diameter of the barrel to allow for access to firearm components without having to remove the muzzle device from the end of the barrel.
1. A muzzle device to be attached at an end of a barrel of a firearm comprising:
A proximal end near the end of the barrel, a distal end, an external surface, a central bore extending between the proximal and distal end and aligned with a bore of the barrel;
the central bore having a diameter substantially equal to the diameter of the bore of the barrel;
A plurality of apertures extending from the central bore to an external surface of the muzzle device, the plurality of apertures each having an external opening, and the plurality of apertures being rearwardly angled from the central bore where the external opening is inclined to face the proximal end; and
At least one chamfer located on the external surface and the chamfer is co-located with at least one aperture.
2. The muzzle device of claim 1 , wherein the at least one aperture co-located with the chamfer is located at the region of the chamfer that is closer to the distal end.
3. The muzzle device of claim 1 , wherein at least one aperture has a smaller diameter than the diameter of the central bore.
4. The muzzle device of claim 1 , wherein the distal end has a greater number of apertures than other regions of the muzzle device.
5. The muzzle device of claim 1 , further comprising at least one supplementary aperture that extends perpendicular from the central bore, the supplementary aperture having an external opening.
6. The muzzle device of claim 5 , further comprising more than one supplementary aperture and at least two supplementary apertures having external openings that face opposite directions from each other.
7. The muzzle device of claim 5 , wherein the supplementary aperture is configured to receive a shaft of an installation tool used to attach the muzzle device to the end of the barrel.
8. The muzzle device of claim 5 , wherein the supplementary aperture is configured to receive a screw, the screw being adjustably located at varying depths.
9. The muzzle device of claim 8 , wherein the screw having a hollowed interior portion, the hollowed interior portion having an external opening and an interior opening that faces the central bore.
10. The muzzle device of claim 1 wherein the distal end having a greater internal volume than other regions of the central bore of the muzzle device.
11. The muzzle device of claim 1 wherein the muzzle device having an external diameter, and the external diameter is the same length as an external diameter of the barrel.
