Abstract

A reticle incorporates an optical center and a plurality of measuring points. The measuring points are formed by a primary vertical line, a primary horizontal line intersecting the primary vertical line at the optical center, a plurality of dots intersecting the primary lines and evenly spaced at a predetermined distance along the primary lines, a plurality of secondary lines intersecting one of the primary lines and evenly spaced between the dots therein. The secondary lines are shorter than 0.2 mil. Alternatively, the reticle further incorporates at least one post on at least one end of the primary lines with post hash marks thereon. Each the intersecting lines forms one of the plurality of measuring points.

Claims

1. A reticle comprising an optical center and a plurality of measuring points, said measuring points formed by a primary vertical line, a primary horizontal line intersecting said primary vertical line at the optical center, a plurality of dots intersecting said primary lines and evenly spaced at a predetermined distance along said primary lines, a plurality of secondary lines intersecting one of said primary lines and evenly spaced between the dots therein, each said intersecting lines forming one of said plurality of measuring points, wherein the secondary lines are shorter than 0.2 mil.

2. The reticle according to claim 1, wherein the a predetermined distance is a mil.

3. The reticle according to claim 1, wherein the dots are 0.2 mil or 0.68 minute round.

4. The reticle according to claim 1, wherein the measuring points also function as aiming points for moving targets, elevation/windage bold-offs, or quick follow-up shots.

5. The reticle according to claim 1, wherein the dots and lines are at least one of acid-etched or laser-engraved on the reticle.

6. The reticle according to claim 5, wherein the lines and dots are further chrome filled.

7. The reticle according to claim 1, wherein the dots and lines are defined in black.

8. The reticle according to claim 1, wherein the reticle is illuminated with a light.

9. The reticle according to claim 1, further comprising posts each at one end of the primary lines.

10. The reticle according to claim 1, wherein the posts are at least one of defined in black and formed to be seen-through so as to be illuminated at different intensities.

11. The reticle according to claim 1, wherein the secondary lines are 0.15 mil long.
