US Patent 9188403 Gas dispersion nozzle for a fire arm silencer

A gas dispersion nozzle for a gun silencer having a nozzle portion with a front end and a rear end and walls enclosing a hollow interior therein. The rear end of the nozzle portion is attached to the gun silencer and the nozzle portion extends into the interior of the gun silencer. The rear end also attaches to a firearm. The walls have channels which direct flow of propellant gases out of the hollow interior and into the interior of the gun silencer at an angle to a path along which the projectile passes when the firearm is discharged. The channels cause the flow of propellant gases to become turbulent or rotational or both and can cause the flow rate of said propellant gases to decrease. The gas dispersion nozzle reduces the report and/or flash produced by the discharge of a firearm.
