Abstract

A suppressor for a firearm includes a casing and a plurality of baffles inside the casing. A retainer is releasably coupled to the casing downstream from the plurality of baffles, and the retainer has a downstream surface. A rear cap is releasably coupled to the casing upstream from the plurality of baffles, and the rear cap has an upstream surface and a downstream surface. A downstream rear cap surface feature is defined by the downstream surface of the rear cap and has a complementary shape to the downstream surface of the retainer. When the rear cap is removed from the casing, the downstream rear cap surface feature can engage with the downstream surface of the retainer to remove the retainer from the casing.

First claim

What is claimed is:

1. A suppressor for a firearm, comprising:
a casing that defines a rear end opposed to a front end;
a plurality of baffles inside said casing;
a retainer releasably coupled to said casing downstream from said plurality of baffles, wherein said retainer has a downstream surface;
a front cap releasably coupled to said front end of said casing downstream from said retainer, wherein said front cap has an upstream surface;
an upstream front cap surface feature defined by said upstream surface of said front cap;
a rear cap releasably coupled to said rear end of said casing upstream from said plurality of baffles, wherein said rear cap has an upstream surface and a downstream surface;
an upstream rear cap surface feature defined by said upstream surface of said rear cap that has a complementary shape to said upstream front cap surface feature;
a downstream rear cap surface feature defined by said downstream surface of said rear cap that has a complementary shape to said downstream surface of said retainer;
wherein when said front cap is removed from said front end of said casing, said upstream front cap surface feature can engage with said upstream rear cap surface feature to remove said rear cap from said rear end of said casing; and
wherein when said rear cap is removed from said rear end of said casing, said downstream rear cap surface feature can engage with said downstream surface of said retainer to remove said retainer from said casing.

2. The suppressor as in claim 1 , wherein said retainer is in threaded engagement with said casing.

3. The suppressor as in claim 1 , wherein said downstream surface of said retainer comprises a plurality of walls that extend axially downstream from said downstream surface of said retainer.

4. The suppressor as in claim 1 , wherein said upstream front cap surface feature extends radially inward from said upstream surface of said front cap and comprises a plurality of vertices separated by a plurality of sides.

5. The suppressor as in claim 1 , wherein when said front cap is removed from said front end of said casing and said rear cap is removed from said rear end of said casing, said rear cap fits inside said front end of said casing to engage with said downstream surface of said retainer.

6. The suppressor as in claim 1 , wherein said downstream rear cap surface feature comprises a plurality of projections that extend axially downstream from said downstream surface of said rear cap.

7. The suppressor as in claim 1 , wherein one of said upstream rear cap surface feature or said upstream front cap surface feature comprises a male fitting and the other of said upstream rear cap surface feature or said upstream front cap surface feature comprises a female fitting.

8. A suppressor for a firearm, comprising:
a casing that defines a rear end opposed to a front end;
a plurality of baffles inside said casing;
a front cap releasably coupled to said front end of said casing downstream from said plurality of baffles, wherein said front cap has an upstream surface;
a retainer releasably coupled to said casing between said plurality of baffles and said front cap, wherein said retainer has a downstream surface;
a rear cap releasably coupled to said rear end of said casing upstream from said plurality of baffles, wherein said rear cap has an upstream surface and a downstream surface;
a downstream rear cap surface feature defined by said downstream surface of said rear cap that has a complementary shape to said downstream surface of said retainer;
wherein when said front cap is removed from said front end of said casing and said rear cap is removed from said rear end of said casing, said downstream rear cap surface feature can engage with said downstream surface of said retainer to remove said retainer from said casing.

9. The suppressor as in claim 8 , wherein said retainer is in threaded engagement with said casing.

10. The suppressor as in claim 8 , wherein said downstream surface of said retainer comprises a plurality of walls that extend axially downstream from said downstream surface of said retainer.

11. The suppressor as in claim 8 , wherein when said front cap is removed from said front end of said casing and said rear cap is removed from said rear end of said casing, said rear cap fits inside said front end of said casing to engage with said downstream surface of said retainer.

12. The suppressor as in claim 8 , wherein said downstream rear cap surface feature comprises a plurality of projections that extend axially downstream from said downstream surface of said rear cap.

13. A suppressor for a firearm, comprising:
a casing;
a front cap;
a plurality of baffles inside said casing;
a retainer releasably coupled to said casing downstream from said plurality of baffles, wherein said retainer has a downstream surface;
a rear cap releasably coupled to said casing upstream from said plurality of baffles, wherein said rear cap has an upstream surface and a downstream surface;
a downstream rear cap surface feature defined by said downstream surface of said rear cap that has a complementary shape to said downstream surface of said retainer;
wherein when said rear cap is removed from said casing, said downstream rear cap surface feature can engage with said downstream surface of said retainer to remove said retainer from said casing.

14. The suppressor as in claim 13 , wherein said retainer is in threaded engagement with said casing.

15. The suppressor as in claim 13 , wherein said downstream surface of said retainer comprises a plurality of walls that extend axially downstream from said downstream surface of said retainer.

16. The suppressor as in claim 13 , wherein when said rear cap is removed from said casing, said rear cap fits inside said casing to engage with said downstream surface of said retainer.

17. The suppressor as in claim 13 , wherein said downstream rear cap surface feature comprises a plurality of projections that extend axially downstream from said downstream surface of said rear cap.

18. The suppressor as in claim 13 , further comprising:
wherein said front cap is releasably coupled to said casing downstream from said plurality of baffles, wherein said front cap has an upstream surface;
an upstream front cap surface feature defined by said upstream surface of said front cap;
an upstream rear cap surface feature defined by said upstream surface of said rear cap that has a complementary shape to said upstream front cap surface feature; and
wherein when said front cap is removed from said casing, said upstream front cap surface feature can engage with said upstream rear cap surface feature to remove said rear cap from said casing.

19. The suppressor as in claim 18 , wherein said upstream front cap surface feature extends radially inward from said upstream surface of said front cap and comprises a plurality of vertices separated by a plurality of sides.

20. The suppressor as in claim 18 , wherein one of said upstream rear cap surface feature or said upstream front cap surface feature comprises a male fitting and the other of said upstream rear cap surface feature or said upstream front cap surface feature comprises a female fitting.
