Abstract: A sighting apparatus for a firearm includes a front sight affixed to an upper surface at a front end of the firearm, and a rear sight affixed to the upper surface at an opposing rear end of the firearm. The rear sight includes a main body and an indexing element positioned thereon. The indexing element has its terminus aligned with the top surface of the rear sight body. The front sight is positioned higher than the rear sight, such that aiming the firearm involves pointing the front sight at the target, then aligning the bottom of the front site with the upper terminus of the indexing element on the rear sight. In one embodiment of the invention, the rear sight has a low-profile that enables the user to regain significant field of view that was blocked by prior art rear sights.
