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.

Claims (41)

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.
