Abstract
A muzzle device for use on a firearm to reduce noise signature and muzzle flash includes a cylindrical housing. The cylindrical housing defines a first chamber and a second chamber with a longitudinal axis extending therethrough. The first chamber has at least one port that extends outward therefrom. The second chamber has at least one slot that extends outward therefrom. The at least one port forms an acute angle with the longitudinal axis that extends forward toward the slot. The angle formed by the at least one port and the longitudinal axis being about 50 degrees. The cylindrical housing defines an outer annular groove being in communication with the at least one port. The at least one port is in communication with an aft surface of the annular groove.
Claims31
A flash suppressor for a firearm having a barrel with a muzzle end, said flash suppressor comprising:
- a housing mountable on said muzzle end of said barrel and defining a first chamber positionable adjacent to said muzzle end, and a second chamber positioned adjacent to said first chamber, said first and second chambers surrounding an axis extending longitudinally along said housing;
- a plurality of ports located in said housing and providing fluid communication directly between said first chamber and the ambient;
- a plurality of elongate slot openings positioned in said housing and providing fluid communication directly between said second chamber and the ambient, each of said slot openings having a longitudinal aspect oriented along said axis, each of said slot openings being longitudinally aligned with a respective one of said ports, said ports being angularly oriented toward said second chamber with respect to said axis to direct high pressure gas over said slot openings.
A flash suppressor for a firearm having a barrel with a muzzle end, said flash suppressor comprising:
- a housing mountable on said muzzle end of said barrel and defining a first chamber positionable adjacent to said muzzle end, and a second chamber positioned adjacent to said first chamber, said first and second chambers surrounding an axis extending longitudinally along said housing;
- at least one port located in said housing and providing fluid communication directly between said first chamber and the ambient;
- at least one elongate slot opening positioned in said housing and providing fluid communication directly between said second chamber and the ambient, said at least one slot opening having a longitudinal aspect oriented along said axis, said at least one slot opening being longitudinally aligned with said at least one port, said at least one port being angularly oriented toward said second chamber with respect to said axis to direct high pressure gas over said at least one slot opening.
A firearm having a flash suppressor, said firearm comprising:
- a barrel having a muzzle end;
- a housing mounted on said muzzle end of said barrel and defining a first chamber positioned adjacent to said muzzle end, and a second chamber positioned adjacent to said first chamber, said first and second chambers surrounding an axis extending longitudinally along said housing;
- a plurality of ports located in said housing and providing fluid communication directly between said first chamber and the ambient;
- a plurality of elongate slot openings positioned in said housing and providing fluid communication directly between said second chamber and the ambient, each of said slot openings having a longitudinal aspect oriented along said axis, each of said slot openings being longitudinally aligned with a respective one of said ports, said ports being angularly oriented toward said second chamber with respect to said axis to direct high pressure gas over said slot openings.
