Abstract

An accessory mount includes a barrel connector and multiple accessory connectors. The barrel connector removably assembles the accessory mount to the barrel of the firearm in axial alignment with the firing axis of the firearm. The accessory mount includes one or more of the accessory connectors to securely and removably assemble accessories to thereto. The accessory connectors include axial alignment features to axially align accessories with the firing axis and/or rotational alignment features to align the accessory alignment with the firing axis. Accessory connectors also include that enable an accessory to be securely assembled to the accessory mount in different rotational orientations.

First claim

What is claimed is:

1. A muzzle end accessory mount for a firearm, the accessory mount comprising:
a proximal portion and a distal portion, the proximal and distal portions defining a passageway for passage of a bullet;
a barrel connector internally threaded and having a first diameter;
a first accessory connector constructed and arranged to removably connect with a first accessory in axial alignment with a barrel of the firearm and in a plurality of rotational orientations about a firing axis of the firearm, wherein said first accessory connector includes internal threads and has a second diameter larger than the first diameter to engage corresponding threads of the first accessory; and
a second accessory connector constructed and arranged to removably connect with a second accessory in axial alignment with the firing axis of the firearm, said second accessory connector includes threads to engage corresponding threads of the second accessory.

2. The muzzle end accessory mount of claim 1 , wherein said first accessory connector is positioned at said distal portion.

3. The muzzle end accessory mount of claim 1 , further comprising a compression element that is compressed between the first accessory and said first accessory connector to provide the plurality of rotational orientations about the firing axis of the firearm for the first accessory.

4. The muzzle end accessory mount of claim 3 , wherein the compression element is a crush washer.

5. The muzzle end accessory mount of claim 3 , in combination with the first accessory.

6. The muzzle end accessory mount of claim 3 , in combination with the first accessory, wherein said first accessory is selected from the group consisting of a compensator and a muzzle brake.

7. The muzzle end accessory mount of claim 1 , wherein said second accessory connector is positioned at least partially between said first accessory connector and said proximal portion.

8. The muzzle end accessory mount of claim 1 , wherein said second accessory connector is positioned at least partially on a peripheral outer surface of said accessory mount.

9. The muzzle end accessory mount of claim 8 , wherein said second accessory connector is positioned at a radial distance from the firing axis that is larger than said first accessory connector.

10. The muzzle end accessory mount of claim 1 , in combination with the second accessory.

11. The muzzle end accessory mount of claim 1 , in combination with the second accessory, wherein said second accessory includes a silencer.

12. The muzzle end accessory mount of claim 1 , wherein said internally threaded barrel connector is constructed and arranged to removably connect said proximal portion to the barrel of the firearm with said passageway in axial alignment with the firing axis of the firearm.

13. The muzzle end accessory mount of claim 1 , wherein said internally threaded barrel connector includes an inner conical surface configured to engage features of the barrel of the firearm.

14. The muzzle end accessory mount of claim 1 , in combination with the firearm.

15. The muzzle end accessory mount of claim 1 , wherein said accessory mount has an inner surface defining the passageway, and wherein said first accessory is positioned on said inner surface.

16. The muzzle end accessory mount of claim 1 , wherein the first accessory connector is constructed and arranged such that at least a portion of the first accessory, when mounted to the barrel, lies flush with a distal end of the barrel.

17. The muzzle end accessory mount of claim 1 , wherein the first diameter is positioned at the proximal portion and the second diameter is positioned at the distal portion of the accessory mount.

18. The muzzle end accessory mount of claim 1 , wherein the distal portion has an outer peripheral surface that is spaced apart from said first accessory connector and said second accessory connector.

19. A muzzle end accessory mount for a firearm, the accessory mount comprising:
a proximal portion and a distal portion, the proximal and the distal portions defining a passageway for passage of a bullet, the accessory mount having an outer peripheral surface, and an inner surface defining the passageway;
a barrel connector internally threaded and having a first diameter;
a first accessory connector constructed and arranged to removably connect with a first accessory in axial alignment with a barrel of the firearm and in a plurality of rotational orientations about a firing axis of the firearm, wherein said first accessory connector includes internal threads and has a second diameter larger than the first diameter to engage corresponding threads of the first accessory; and
a second accessory connector constructed and arranged to removably connect with a second accessory in axial alignment with the firing axis of the firearm, wherein said second accessory connector is positioned on said outer peripheral surface.

20. The muzzle end accessory mount of claim 19 , wherein the outer peripheral surface includes a conical surface configured to engage the second accessory.

21. The muzzle end accessory mount of claim 20 , wherein the conical surface is aligned with the first accessory connector.

22. The muzzle end accessory mount of claim 19 , wherein the first accessory connector is constructed and arranged such that at least a portion of the first accessory, when mounted to the barrel, lies flush with a distal end of the barrel.
