Abstract

An apparatus and system are provided for a firearm suppressor. The system, in one embodiment, includes an elongated core comprising at least one series of ports extending radially from a bore to an exterior surface of the core, where the at least one series of ports is disposed linearly along a longitudinal axis of the core, and where the elongated core comprises at least one trough formed in the exterior surface of the core. The system also includes a baffle sleeve disposed around the core, the baffle sleeve having at least one uninterrupted fluid pathway extending along the exterior surface of the baffle sleeve and formed by interdigitated baffle ridges, and an outer tube disposed around the baffle sleeve.

Claims (20)

1. A firearm suppressor comprising:

an elongated core comprising at least one series of ports extending radially from a bore to an exterior surface of the core, where the at least one series of ports is disposed linearly along a longitudinal axis of the core, and where the elongated core comprises at least one trough formed in the exterior surface of the core;

a baffle sleeve disposed around the core, the baffle sleeve having a plurality of uninterrupted fluid pathways extending longitudinally along the exterior surface of the baffle sleeve and formed by interdigitated baffle ridges; and an outer tube disposed around the baffle sleeve; and

wherein the baffle sleeve further comprises a plurality of port openings that fluidly couple an interior surface of the baffle sleeve with an exterior surface of the baffle sleeve, and where at least one of the plurality of port openings is positioned such that the at least one of the plurality of port openings is aligned with at least one port of the at least one series of ports.

2. The firearm suppressor of claim 1 , where the at least one series of ports extending radially from the bore comprises two series of ports extending radially from the bore, and where the at least one trough is disposed between the two series of ports.

3. The firearm suppressor of claim 1 , where each port of the at least one series of ports is formed with helical grooves that direct fluids to form a vortex.

4. The firearm suppressor of claim 1 , where each port of the at least one series of ports extends outward radially from the bore at a non-orthogonal angle.

5. The firearm suppressor of claim 4 , where each port of the at least one series of ports is angled toward an end of the elongated core.

6. The firearm suppressor of claim 5 , where the non-orthogonal angle is in the range of between about 5 and 80 degrees.

7. The firearm suppressor of claim 6 , where the non-orthogonal angle is 65 degrees.

8. The firearm suppressor of claim 1 , where at least one of the interdigitated baffle ridges terminates adjacent one of the plurality of port openings.

9. The firearm suppressor of claim 1 , where the baffle sleeve further comprises a plurality of trough openings that fluidly couple an interior surface of the baffle sleeve with an exterior surface of the baffle sleeve, and where at least one of the plurality of trough openings is positioned such that the at least one of the plurality of trough openings is aligned with the trough.

10. The firearm suppressor of claim 1 , further comprising a baffle tube retainer and a spacer tube, where the spacer tube couples to and extends longitudinally from an end of the elongated core, and where the baffle tube retainer is disposed between the elongated core and the spacer tube and is configured to couple the baffle sleeve to the elongated core.

11. The firearm suppressor of claim 10 , further comprising at least one disk-shaped forward baffle coupled to the spacer tube, where the at least one disk-shaped forward baffle comprises an irregular surface having a plurality of radially extending openings.

12. The firearm suppressor of claim 11 , where the at least one forward baffle comprises a plurality of forward baffles, each of the plurality of forward baffles comprising a key in an opening that is configured to engage the spacer tube, where each key maintains a rotational position of its respective forward baffle with respect to the spacer tube, and where each of the plurality of forward baffles is rotationally offset with respect to an adjacent one of the plurality of forward baffles such that the radially extending openings of one of the plurality of forward baffles do not align with the radially extending openings of an adjacent forward baffle of the plurality of forward baffles.

13. The firearm suppressor of claim 11 , where the elongated core further comprises a base having a diameter greater than the elongated core, where the base forms a platform for receiving the baffle sleeve and the outer tube.

14. The firearm suppressor of claim 13 , where the outer tube couples to the base.

15. The firearm suppressor of claim 14 , where the outer tube further comprises an annular ridge disposed adjacent an end of the outer tube, where the annular ridge is configured to engage with and maintain the at least one forward baffle within the outer tube.

16. The firearm suppressor of claim 1 , where the outer tube further comprises a plurality of teeth at one end of the outer tube.

17. The firearm suppressor of claim 16 , where the outer tube further comprises a plurality of venturi tabs formed adjacent the plurality of teeth, where each of the plurality of venturi tabs comprises a triangular-shaped tab angled inward such that each of the plurality of venturi tabs impedes the flow of gasses from the firearm suppressor.
