  • Laser welded firearm sound suppressors
    Patent number: 10088259
    Abstract: Various techniques are provided to assemble, manufacture, and operate firearm sound suppressors. In one example, a sound suppressor for a firearm includes a baffle; a spacer abutted to the baffle; and a circumferential laser weld joining the baffle and the spacer. In another example, a sound suppressor for a firearm includes a plurality of baffles; a plurality of spacers; a substantially tubular housing surrounding the baffles and the spacers; wherein the housing and the spacers define an annular volume surrounding the spacers; an aperture in a circumfery of at least one of the spacers; and wherein the aperture is adapted to direct combustion gases in a radial direction from within the spacer into the annular volume to reduce ejection port flash of the firearm. Additional suppressor embodiments and related methods are also provided.
