Abstract
The present invention is directed to a sighting device having an aperture with a series of visual reference points framing the aperture that are used in concert with a vertical front sight to quickly acquire and precisely aim a firearm at a target. The visual reference points framing the aperture are readily discernable to a shooter, even though the reference points and the aperture may be visually out of focus as the shooter concentrates on the target. The visual reference points framing the aperture are in the form of edges, angles, and vertices that take advantage of the human eye's natural acuity for angular geometric shapes as the shooter visually coordinates the position of the present invention with the vertical front sight and a target. The unobstructed field of view provided by the aperture portion of the present invention combined with readily discernable geometrically shaped visual reference points framing the aperture assist the shooter in precisely aiming a firearm, or other projectile propulsion device, at a target. In addition, rapid and accurate adjustments, or refinements, in the shooter's aim at a target are readily effected with the present invention.
