  • Patent number: 8807272
    Abstract: A sound suppressor for firearms (such as hand guns and rifles) has a tubular body with a first end cap adjacent the barrel of the firearm, and a 5 second end cap with exhaust vents for the gases. A plurality of baffles, each having a passage for the bullet, are provided in the body intermediate the first-and-second end caps. Each baffle has a plurality of vents in the outer portion, the vents forming at least one path for the flow of the major portion of the gases through the suppressor body. By angularly offsetting the vents of adjacent baffles, the gas path(s) are made tortuous to further slow the gas flow. The baffle adjacent the first end cap can be a deflecting baffle, where the vents deflect the gases outwardly towards the body. The body may be connected to the barrel of the firearm by screw-threads or a bayonet coupling; and a flash eliminator may be connected to the body adjacent the second end cap.
