Abstract

A firearm accessory and associated components and methods. The firearm can be a firearm sight, such as a red dot type sight. The firearm accessory includes a base configured to mount to at least first and second different mounting adaptors to permit selective mounting of the firearm accessory to a firearm via the first mounting adaptor or the second mounting adaptor.

Claims (22)

1 . A firearm sight selectively usable with a first firearm sight connection structure and a second firearm sight connection structure for connecting the firearm sight to a firearm, the second firearm sight connection structure being differently configured compared to the first firearm sight connection structure, the firearm accessory comprising:

a base including mount connection structure configured to selectively connect to the first firearm sight connection structure and the second firearm sight connection structure to permit mounting of the firearm sight on a firearm, the mount connection structure including a hole extending through the base, the hole being configured to receive a first fastener when the firearm sight is mounted on the firearm using the first firearm sight connection structure and being configured to receive a second fastener when the firearm sight is mounted on the firearm using the second firearm sight connection structure; and

a sighting portion supported by the base, the sighting portion being configured to assist a shooter of the firearm in aiming the firearm.

2 . The firearm sight of claim 1 , wherein the hole is sized and shaped to receive the first fastener at a first position within the hole when the firearm sight is mounted on the firearm using the first firearm sight connection structure and to receive the second fastener at a second position within the hole when the firearm sight is mounted on the firearm using the second firearm sight connection structure.

3 . The firearm sight of claim 1 , wherein the hole includes a first hole section and a second hole section, the first hole section being configured to receive the first fastener for mounting the firearm sight on the firearm using the first firearm sight connection structure, and the second hole section being configured to receive the second fastener for mounting the firearm sight on the firearm using the second firearm sight connection structure.

4 . The firearm sight of claim 3 , wherein the first and second hole sections partially overlap.

5 . The firearm sight of claim 3 , wherein the hole includes a first edge segment bordering the first hole section and a second edge segment bordering the second hole section, the first edge segment being configured to engage the first fastener when the firearm sight is mounted on the firearm using the first firearm sight connection structure, the second edge segment being configured to engage the second fastener when the firearm sight is mounted on the firearm using the second firearm sight connection structure.

6 . The firearm sight of claim 5 , wherein the first edge segment is configured to be free of engagement with the second fastener when the firearm sight is mounted on the firearm using the second firearm sight connection structure, and the second edge segment is configured to be free of engagement with the first fastener when the firearm sight is mounted on the firearm using the first firearm sight connection structure.

7 . The firearm sight of claim 3 , wherein the hole includes a first edge segment bordering the first hole section and a second edge segment bordering the second hole section, the first and second edge segments each having a partially circular cross-sectional shape.

8 . The firearm sight of claim 7 , wherein the first and second edge segments each have a semi-circular cross-sectional shape.

9 . The firearm sight of claim 1 , wherein the hole comprises a slot.

10 . The firearm sight of claim 9 , wherein the slot is arranged at a skew angle relative to a sighting axis of the sighting portion along which the user looks to aim the firearm using the firearm sight.

11 . The firearm sight of claim 1 , wherein the hole is a first hole, and wherein the mount connection structure includes a second hole extending through the base, the second hole being configured to receive a third fastener when the firearm sight is mounted on the firearm using the first firearm sight connection structure and being configured to receive a fourth fastener when the firearm sight is mounted on the firearm using the second firearm sight connection structure.

12 . The firearm sight of claim 11 , wherein the second hole is a mirror image of the first hole.

13 . The firearm sight of claim 1 , wherein the sighting portion defines a sighting axis along which the user looks forward through to aim the firearm using the firearm sight, the mount connection structure including a socket disposed on an underside of the base, the socket being disposed forward of the hole.

14 . The firearm sight of claim 13 , wherein the socket is configured to receive the first firearm sight connection structure of the first mount when the firearm sight is mounted on the firearm using the first sight connection structure, and the socket is configured to receive the second firearm sight connection structure of the second mount when the firearm sight is mounted on the firearm using the second sight connection structure.

15 . The firearm sight of claim 14 , wherein the socket is a first socket, and wherein the mount connection structure including a second socket disposed on the underside of the base, the second socket being disposed rearward of the hole.

16 . The firearm sight of claim 15 , wherein the second socket is configured to receive the first firearm sight connection structure of the first mount when the firearm sight is mounted on the firearm using the first sight connection structure.

17 . The firearm sight of claim 16 , wherein the second socket has a circular cross-sectional shape.

18 . The firearm sight of claim 15 , wherein the first socket includes a first socket section and a second socket section, the first socket section being configured to receive the first firearm sight connection structure for mounting the firearm sight on the firearm using the first firearm sight connection structure, and the second socket section being configured to receive the second firearm sight connection structure for mounting the firearm sight on the firearm using the second firearm sight connection structure.

19 . The firearm sight of claim 1 , wherein the sighting portion comprises a red dot sighting portion.

20 . The firearm sight of claim 1 , wherein the sighting portion includes a lens and a lens support connected to the base, the lens support securing the lens in position with respect to the base.
