ABSTRACT:
A sound suppression system having a sound suppression chamber formed from a longitudinally extending tubular housing. One end of the tubular housing is closed by an end plug which has a bore through which passes one end of a tubular member. The tubular member comprises a gun barrel having a cylindrical sleeve surrounding a predetermined length of the gun barrel. The tubular member has a plurality of tubular passages each of which have their one end in communication with the bore of the gun barrel and their other end longitudinally displaced therefrom adjacent the end of the gun barrel to place them in communication with the interior of the sound suppression chamber. A baffle having a cylindrical body approximating the interior diameter of the tubular housing is positioned within the tubular housing. Both the interior of the tubular housing and the outer cylindrical housing of the baffle are threaded so that the baffle may be adjustably positioned through the length of the tubular housing. The baffle has a bore which is aligned with the bore of the gun barrel to allow a bullet to pass therethrough. The end of the baffle adjacent the end of the gun barrel has a conical or convex gas deflection surface that is positioned in alignment with the ends of the tubular passages where they exit the tubular member. The outer end of the tubular housing has an end plug closing it and likewise has a bore in its center axially aligned with the bore of the gun barrel.
