Abstract

In one embodiment, the reticle for a projectile weapon aiming system comprises a primary horizontal sight line, a primary vertical sight line which intersects the primary horizontal sight line to define a primary aiming point, a windage grid, a ballistics grid, and a range finder grid.

Claims

1. A reticle for a projectile weapon aiming system, said reticle comprising:

a primary horizontal sight line;

a primary vertical sight line intersecting the primary horizontal sight line to define a primary aiming point and four quadrants of substantially equal size;

a windage grid;

a ballistics grid; and

a range finder grid;

wherein the range finder grid comprises a plurality of vertically spaced-apart, vertically aligned crosshairs positioned entirely within a lower-left hand quadrant of the reticle;

wherein each of the vertically aligned crosshairs defines a substantially identical reading at a predetermined range; and

wherein an inner half of the vertically aligned crosshairs is provided in a first color and an outer half of the vertically aligned crosshairs is provided in a second color that is different than the first color.

2. The reticle of claim 1, wherein the primary horizontal sight line includes a horizontal central portion extending radially from the primary aiming point, and a horizontal post portion being thicker than the horizontal central portion and extending radially from the horizontal central portion.

3. The reticle of claim 1, wherein the primary vertical sight line includes a vertical lower portion extending radially from the primary aiming point and a vertical upper central portion extending radially from the primary aiming point, and a vertical post portion being thicker than the vertical central portion and extending radially from the vertical upper central portion.

4. The reticle of claim 1, wherein the windage grid comprises a plurality of horizontal aiming marks spaced apart along the primary horizontal sight line.

5. The reticle of claim 4, wherein the horizontal aiming marks comprise primary horizontal aiming marks and secondary horizontal aiming marks.

6. The reticle of claim 5, wherein the primary horizontal aiming marks have a length which is greater than the secondary horizontal aiming marks.

7. The reticle of claim 6, wherein one or more of the primary horizontal aiming marks have an associated unique symbol indicating the relative horizontal distance from the primary aiming point.

8. The reticle of claim 1, wherein the ballistics grid comprises a plurality of vertical aiming marks spaced apart along the primary vertical sight line.

19. The reticle of claim 1, wherein a plurality of the vertically aligned crosshairs are provided with a unique symbol corresponding to the range of its reading.

20. The reticle of claim 1, wherein moving in a downward direction, the vertically aligned crosshairs correspond to readings that increase in equal increments.

21. The reticle of claim 1, wherein the vertically aligned crosshairs define a 48×

48 centimeter reading.

9. The reticle of claim 9, wherein the vertical aiming marks comprise primary, secondary, and tertiary aiming marks.

10. The reticle of claim 9, wherein the primary vertical aiming marks have a length which is greater than the secondary vertical aiming marks and the tertiary vertical aiming marks, and wherein the secondary vertical aiming marks have a length which is greater than the tertiary vertical aiming marks.

11. The reticle of claim 10, wherein the secondary vertical aiming marks comprise a right end portion extending upward in a direction substantially parallel to the primary vertical sight line and a left end portion extending downward in a direction substantially parallel to the primary vertical sight line.

12. The reticle of claim 11, wherein one or more of the primary and secondary vertical aiming marks have an associated unique symbol indicating the relative vertical distance from the primary aiming point.
