Abstract

The present invention provides an apparatus for aiding in the alignment of a scope of a firearm. The apparatus includes a light generation device and a level indicator. The light generation device is attachable to the firearm and is for generating a reference beam. The reference beam may be a horizontal, vertical, or cross-hair line beam. When the level indicator indicates a level state, the reference beam generated by the light generation device is also level. Typically, the level reference beam is projected against a flat surface and is used as a reference to line up the crosshairs of a scope attached to the firearm.

Claims

1. An apparatus for aiding in the alignment of a scope of a firearm, the apparatus comprising:

a light generation device attachable to the firearm, the light generation device for generating a reference beam; and

a level indicator, wherein the reference beam is level with respect to a horizontal plane when the level indicator indicates a level state.

2. The apparatus of claim 1 wherein the reference beam is a line-shaped beam.

3. The apparatus of claim 1 wherein the reference beam comprises a plurality of line-shaped beams.

4. The apparatus of claim 1 wherein the reference beam comprises a series of dots that taken together form a line.

5. The apparatus of claim 1 wherein the reference beam comprises a series of dashes that taken together from a line.

6. The apparatus of claim 1 wherein the light generation device comprises a laser.

7. The apparatus of claim 6 wherein the laser is a solid-state laser module.

8. The apparatus of claim 1 wherein the light generation device fits into the bore of the firearm.

9. The apparatus of claim 8 wherein the light generation device further comprises:

a bore connector having a first end and a second end, wherein the first end fits into the bore of the firearm; and

a light generator for generating the reference beam, the light generator being attached to the second end of the bore connector.

10. The apparatus of claim 9 wherein the first end of the bore connector is also attachable to the firearm by inserting the first end into a bore adapter contained within the bore of the firearm.

11. The apparatus of claim 9 wherein the first end of the bore connector is also attachable to the firearm by insertion into a bore connector receptacle attached to the firearm.

12. The apparatus of claim 1 wherein the light generation device further includes a reference beam lens, wherein the reference beam is generated by passing light through the reference beam lens.

13. The apparatus of claim 12 wherein the level indicator is mounted on the reference beam lens.

14. The apparatus of claim 12 wherein the reference beam lens is a line-generating lens.

15. The apparatus of claim 1 wherein the level indicator is a bubble-type level.

16. The apparatus of claim 1 wherein the light generation device generates a horizontal reference beam when level.

17. The apparatus of claim 1 wherein the light generation device generates a vertical reference beam when level.

18. The apparatus of claim 1 wherein the light generation device generates a cross-hair reference beam.

19. The apparatus of claim 1, wherein the light generation device includes a bore connector, wherein the light generation device is attachable to the firearm by inserting the bore connector in a bore of the firearm.

20. A system for creating at least one level reference beam, the system comprising:

a housing configured to attach to a provided light generation device, the light generation device attachable to a provided firearm;

a lens contained within the housing that creates at least one reference beam when a light from the light generation device is passed through the lens, the reference beam being adjustable; and

a level indicator mounted on the housing, wherein the at least one reference beam is level with respect to a horizontal plane when the level indicator indicates a level state.

21. The system of claim 20 wherein the housing includes a structure for aligning the lens such that the reference beam will be level when the level indicator indicates a level state.

22. The system of claim 21 wherein the structure for aligning the lens is one or more grooves in the housing that align with one or more grooves formed in the lens.

23. The system of claim 21 wherein the structure for aligning the lens is a frame in which the lens fits.

24. The system of claim 20 wherein the level indicator is a bubble-type level.

25. The system of claim 20 wherein the lens creates one reference beam.

26. The system of claim 20 wherein the lens generates a horizontal reference beam when level.

27. The system of claim 20 wherein the lens generates a vertical reference beam when level.

28. The system of claim 20 wherein the lens generates a cross-hair reference beam.

29. The system of claim 20, wherein the light generation device includes a bore connector, wherein the light generation device is attachable to the firearm by inserting the bore connector in a bore of the firearm.
