Patent ID: 8820473

Claim:
A gas dispersion nozzle for a firearm silencer, comprising: a) a nozzle portion having a front end and a rear end and side walls enclosing a hollow interior therein through which hollow interior a projectile and propellant gases pass; b) said rear end of said nozzle portion having a base portion to attach said nozzle portion to said firearm silencer and to extend said nozzle portion into an interior of said firearm silencer, wherein said base portion has an opening and walls enclosing a hollow interior therein through which a projectile and propellant gases pass, wherein said walls of said base portion have internal threads to attach said nozzle portion to a barrel of a firearm through said opening of said base portion, wherein said threads extend from said opening inward, and wherein only a threaded portion of said barrel is extendable into said hollow interior of said base portion; and c) said side walls of said nozzle portion having channels which direct the flow of said propellant gases out of said hollow interior at an angle to a path along which said projectile passes, wherein said channels are not perpendicular to the longitudinal axis of said hollow interior of said nozzle portion, thereby causing the flow of said propellant gases to be rotational and to create a vortex.
