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, comprising:
an accessory mount having a proximal portion, a distal portion and a body, the accessory mount body defining a passageway between said proximal portion and said distal portion for passage of a bullet; a first accessory connector of said accessory mount constructed and arranged to removably connect with a first muzzle end accessory in axial alignment with a barrel of the firearm and in a plurality of rotational orientations about the firing axis of the firearm; and a second accessory connector of said accessory mount constructed and arranged to removably connect with a second muzzle end accessory in axial alignment with the firing axis of the firearm.

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

3 . The muzzle end accessory mount of claim 2 , wherein said first accessory mount includes threads to engage corresponding threads of the first accessory.

4 . The muzzle end accessory mount of claim 3 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.

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

6 . The muzzle end accessory mount of claim 4 , in combination with the first accessory.

7 . The combination of claim 6 , wherein said first accessory is selected from a group consisting of a compensator and a muzzle brake.

8 . 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 of said accessory mount body.

9 . 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 body.

10 . The muzzle end accessory mount of claim 9 , wherein said second accessory connector is positioned about said accessory mount body at a larger diameter than said first connector.

11 . The muzzle end accessory mount of claim 10 , wherein said second accessory connector includes threads and a conical surface that engage corresponding features of the second accessory.

12 . The muzzle end accessory of claim 11 , in combination with the second accessory.

13 . The combination of claim 12 , wherein said second accessory includes a silencer.

14 . The muzzle end accessory mount of claim 1 , further comprising:
a barrel connector constructed and arranged to removably connect said proximal portion of said accessory mount body to the barrel of the firearm with said passageway in axial alignment with a firing axis of the firearm.

15 . The muzzle end accessory mount of claim 14 , wherein said barrel connector includes threads and a conical surface that engage corresponding features of the barrel of the firearm.

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

17 . A muzzle end accessory mount for a firearm, comprising:
an accessory mount having a body, a proximal portion and a distal portion, the accessory mount body defining a passageway between said proximal portion and said distal portion for passage of a bullet; a barrel connector constructed and arranged to removably connect said proximal portion of said accessory mount to a barrel of the firearm with said passageway in axial alignment with a firing axis of the firearm, said barrel connector including threads and a conical surface that engage corresponding features of the barrel of the firearm; a first accessory connector of said accessory mount body constructed and arranged to removably connect with a first muzzle end accessory in axial alignment with the barrel of the firearm, wherein said first accessory connector is positioned at said distal portion of said accessory mount body and includes threads to engage corresponding threads of the first accessory and a compression element that is compressed between the first accessory and said first accessory connector to enable the first accessory to be rotationally aligned in a plurality of rotational orientations about the firing axis of the firearm for the first accessory; and a second accessory connector of said accessory mount body positioned at least partially on a peripheral outer surface of said accessory mount body and about said accessory mount body at a larger diameter than said first connector, said second accessory connector constructed and arranged to removably connect with a second muzzle end accessory in axial alignment with the firing axis of the firearm, wherein said second accessory connector includes threads and a conical surface that engage corresponding features of the second accessory.

18 . The muzzle end accessory mount of claim 17 , in combination with the first accessory, the second accessory, and the firearm.

19 . A method of assembling one or more muzzle end accessories to a firearm, comprising:
securing a first accessory to a first accessory connector of an accessory mount in one of a plurality of rotationally positions about a firing axis of the firearm; and assembling a second accessory about the first accessory and to a second accessory connector of the accessory mount in axial alignment with the firing axis of the firearm.

20 . The method of claim 19 , further comprising:
securing a barrel connector of an accessory mount to a barrel of the firearm in axial alignment with the firing axis of the firearm.
