Abstract

Examples include a threaded coupler for connecting two portions of a firearm sound suppressor housing together. The threaded coupler includes a sound suppressing baffle. Using the coupler and its integrated baffle provides additional sound suppression compared to sound suppressors with other types of connectors between housing portions.

First claim

What is claimed is:

1. A firearm sound suppressor comprising:
a coupler comprising a first portion and a second portion opposed to the first portion, the first portion defining first threads and a first surface and the second portion defining second threads and a second surface; and
a supplemental baffle disposed within and integral with the coupler.

2. The firearm sound suppressor of claim 1 , wherein the first threads and the second threads are defined on an exterior surface of the first portion and the second portion, respectively.

3. The firearm sound suppressor of claim 1 , wherein:
the first threads of the first portion are configured for releasable connection to a first housing of a firearm sound suppressor; and
the second threads of the second portion are configured for releasable connection to a second housing of the firearm sound suppressor.

4. The firearm sound suppressor of claim 3 , wherein the second threads of the second portion are configured for releasable connection to an end cap.

5. The firearm sound suppressor of claim 3 , wherein, upon connection to the first housing, the first surface of the first portion is configured to apply a compressive force to an adjacent sound suppression module disposed within first housing.

6. The firearm sound suppressor of claim 3 , wherein the first threads are configured for releasable connection to the first housing in a first direction and the second threads are configured for releasable connection to the second housing in a second direction opposite the first direction.

7. The firearm sound suppressor of claim 1 , wherein the supplemental baffle disposed within at least one of the first portion and the second portion defines a port configured to permit passage of a projectile.

8. A firearm sound suppressor comprising:
a coupler comprising:
a first portion integral with a second portion, the first portion defining first threads and a first surface, the second portion defining second threads and a second surface;
a supplemental baffle disposed within at least one of the first portion and the second portion;

a first housing defining a first portion of a volume having an inside diameter, the first housing comprising:
a first end defining first threads configured for releasable connection to a firearm barrel;
a second end opposite the first end, the second end defining second threads configured for releasable connection to the first threads of the first portion; and

a second housing defining a second portion of the volume having the inside diameter, the second housing comprising:
a first end defining third threads configured for releasable connection to the second threads of the second portion; and
a second end defining fourth threads.

9. The firearm sound suppressor of claim 8 , further comprising a first plurality of sound suppressor modules configured for placement within the first housing and a second plurality of sound suppressor modules configured for placement within the second housing.

10. The firearm sound suppressor of claim 9 , wherein the first surface of the first portion is configured to apply a compressive force to a first adjacent sound suppressor module of the first plurality of sound suppressor modules.

11. The firearm sound suppressor of claim 9 , wherein each sound suppressor module of the plurality further comprises:
a cylinder having an outside diameter less than the inside diameter of the first housing and the second housing; and
a baffle disposed within the cylinder.

12. The firearm sound suppressor of claim 9 , further comprising an end cap configured for releasable connection to the fourth threads of the second housing.

13. The firearm sound suppressor of claim 12 , wherein the end cap is configured to apply a compressive force to a second adjacent sound suppressor module of the second plurality of sound suppressor modules.

14. A firearm sound suppressor kit comprising:
a coupler comprising:
opposed first and second portions, the first portion defining first threads and a first surface, the second portion defining second threads and a second surface;
a supplemental baffle disposed within at least one of the first portion and the second portion;

a first housing defining a first portion of a volume having an inside diameter, the first housing comprising:
a first end defining first threads configured for releasable connection to a firearm barrel;
a second end opposite the first end, the second end defining second threads configured for releasable connection to the first threads of the first portion;

a second housing defining a second portion of the volume having the inside diameter, the second housing comprising:
a first end defining third threads configured for releasable connection to the second threads of the second portion; and
a second end defining fourth threads.

15. The firearm sound suppressor kit of claim 14 , further comprising a plurality of sound suppressor modules configured for placement within at least one of the first housing and the second housing.

16. The firearm sound suppressor kit of claim 14 , further comprising an end cap.

17. The firearm sound suppressor kit of claim 14 , further comprising a firearm that includes the firearm barrel.
