Abstract

A device implementable on a firearm includes a one-piece sight functioning as a rear sight or a front sight when installed on the firearm. The one-piece sight includes a notch and a user-facing side configured with a first surface aligned with the notch and a second surface on two opposite sides of the first surface. The first and second surfaces are sloped at first and second angles, respectively, to reflect an ambient light at different angles.

First claim

What is claimed is:

1. A device implementable on a firearm, comprising:
a one-piece sight functioning as a rear sight or a front sight when installed on the firearm, the one-piece sight comprising:
a base having a first primary side and a second primary side opposite the first primary side; and
a structure extending from a ground plane on the first primary side of the base with a notch at a center of a distal end of the structure that is away from the base,

wherein the structure has a user-facing side configured with a first surface aligned with the notch and a second surface on two opposite sides of the first surface, and
wherein the first and second surfaces are sloped at first and second angles, respectively, with respect to the ground plane to reflect an ambient light at different angles.

2. The device of claim 1 , wherein the first surface generally reflects the ambient light toward a user of the firearm when the device is in use, and wherein the second surface is generally shadowed under the ambient light when the device is in use.

3. The device of claim 1 , wherein the structure has a contrasting wall on the user-facing side thereof, wherein the structure is configured with a ramp protruding from the contrasting wall, and wherein the ramp is aligned with the notch and is disposed between the notch and the ground plane on the first primary side of the base.

4. The device of claim 3 , wherein the first surface is on the ramp and the second surface is on the contrasting wall on two opposite sides of the ramp.

5. The device of claim 4 , wherein the first angle (θ) of the first surface relative to the ground plane is greater than 90°.

6. The device of claim 4 , wherein the second angle (β) of the second surface relative to the ground plane is less than 90°.

7. The device of claim 4 , wherein the first angle (θ) of the first surface relative to the ground plane is greater than 90°, wherein the second angle (β) of the second surface relative to the ground plane is less than 90°, and wherein a difference between the first angle and the second angle is greater than 5°.

8. The device of claim 1 , wherein the second surface generally reflects the ambient light toward a user of the firearm when the device is in use, and wherein the first surface is generally shadowed under the ambient light when the device is in use.

9. The device of claim 1 , wherein the structure has a contrasting wall on the user-facing side thereof, wherein the structure is configured with an indentation on the contrasting wall, and wherein the indentation is aligned with the notch and is disposed between the notch and the ground plane on the first primary side of the base.

10. The device of claim 9 , wherein the first surface is on the indentation and the second surface is on the contrasting wall on two opposite sides of the indentation.

11. The device of claim 10 , wherein the first angle (θ) of the first surface relative to the ground plane is less than 90°.

12. The device of claim 10 , wherein the second angle (β) of the second surface relative to the ground plane is greater than 90°.

13. The device of claim 10 , wherein the first angle (θ) of the first surface relative to the ground plane is less than 90°, wherein the second angle (β) of the second surface relative to the ground plane is greater than 90°, and wherein a difference between the second angle and the first angle is greater than 5°.

14. The device of claim 1 , wherein the one-piece sight is a monolithic piece made of metal or polymer.

15. The device of claim 1 , wherein the one-piece sight further comprises:
a mounting portion extending from the second primary side of the base and configured to mate with a dovetail rail or a groove on the firearm to result in the mounting portion being received in the dovetail rail or the groove when the one-piece sight is installed on the firearm.

16. A device implementable on a firearm, comprising:
a one-piece sight functioning as a rear sight or a front sight when installed on the firearm, the one-piece sight comprising a notch and a user-facing side configured with a first surface aligned with the notch and a second surface on two opposite sides of the first surface,
wherein the first and second surfaces are sloped at first and second angles, respectively, to reflect an ambient light at different angles.

17. The device of claim 16 , wherein the first surface generally reflects the ambient light toward a user of the firearm when the device is in use, and wherein the second surface is generally shadowed under the ambient light when the device is in use.

18. The device of claim 16 , wherein the first angle (θ) of the first surface relative to a ground plane on the one-piece sight is greater than 90°.

19. The device of claim 16 , wherein the second angle (β) of the second surface relative to a ground plane on the one-piece sight is less than 90°.

20. The device of claim 16 , wherein the first angle (θ) of the first surface relative to a ground plane on the one-piece sight is greater than 90°, and wherein the second angle (β) of the second surface relative to the ground plane is less than 90°, and wherein a difference between the first angle and the second angle is greater than 5°.
