The present invention relates to a suppressor that is configured to be attached to or be part of the barrel of a firearm or air gun to reduce the amount of noise and visible muzzle flash generated by firing a projectile.
2) Description of Related ArtFirearm suppressors typically include a series of stacked baffles received into and secured by a cylindrical housing that is attached to the muzzle of a gun barrel. The baffles stack is designed to reduce the pressure, temperature, and velocity of projectile gas that escapes the firearm muzzle when the firearm is discharged. Typically, improvements to suppressor involves varying designs to the baffles or the baffle stack as shown in U.S. Pat. No. 9,239,201. In this disclosure, each baffle includes a frusto-conical sidewall having an apex opposite a base. The apex includes an axial bore and is disposed towards the receiving bore. The base is disposed toward the discharge bore. The apex includes a semi-circular cut from the sidewall into the axial bore, forming a semi- circular protrusion. The disadvantage is that tremendous pressure is placed on the baffle as the gas is redirected at an extreme angle reducing the life and usefulness of the suppressor.
Accordingly, it is an object of the present invention to provide for a unique baffle stack that redirects expanding gases asymmetrically to create turbulence in the gas stream and further reduce the noise reduction ability of the suppressor.
SUMMARY OF THE INVENTIONThe above objectives are accomplished according to the present invention by providing a firearm suppressor for reducing the amount of noise generated from a firearm comprising: a baffle stack having a plurality of baffles received in an outer tube wherein a first baffle is received into an adjacent baffle; a piston assembly and an endcap removably attached to the outer tube; a piston housing, piston cap and piston spring included in the piston assembly; a first concave section defined in an aperture including in at least one baffle; a second concave section defined in an aperture including in at least one baffle wherein the first concave section and the second concave section are offset relative to a diameter bisecting the baffle; a plurality of ports defined in the outer tube disposed forward of a midpoint in the outer tube configured to shift the center of mass to the rear of the outer tube; and, an end cap removably attached to the outer tube.
A first concave section and the second concave section can be disposed on the same side of the diameter bisecting the baffle. A first baffle can have a height less than a second baffle. An engagement ring can be defined in at least one baffle configured to receive a lower edge of an adjacent baffle to create the baffle stack. A sloped upper side can extend from the engagement ring and terminate at the aperture of at least one baffle. A short lip and a long lip can be included in the aperture. The first concave section and the second concave section can be disposed between the short lip and the long lip.
A first set of ports can be defined in the outer tube that are offset relative to a second set of ports defined in the outer tube. The ports can be in any number of arrangement. In one embodiment, the plurality of ports are disposed forward of a midpoint in the outer tube configured to shift the center of mass to the rear of the outer tube.
