Abstract:
1. A rear aperture sight for use in conjunction with a front sight post sight on a rifle, the front sight post having a horizontal top edge and vertical side edges, said rear aperture sight comprising: a rear sight adapted to be mounted on the rifle, said rear sight having a horizontally elongated aperture formed therein having height and width dimensions, said width dimension being greater than said height dimension, said height dimension being of such a value that said aperture is adapted to cause the horizontal top edge of the front sight post and a horizontal edge of a target to be more sharply focused than if viewed with the naked eye, said width dimension being of such a value that an area defined by said aperture is greater than an area defined by a circular aperture having a diameter equal to said height dimension, thereby permitting more light to pass through said aperture than through the circular aperture, and causing the front sight post and the target to appear brighter than if viewed through the circular aperture.
