Abstract
An aiming sight for devices that shoot projectiles having a housing with an interior. A sight element is positioned within the interior by means of adjustment threads. The adjustment threads pass through channels in the sides of the front sight element so that the front sight element is movable along the adjustment threads from the bottom to the top of the housing. The sight element has a sighting aperture through which a specific target point, intended for penetration by an arrow, is visible. The sighting aperture may be constructed as a front sighting aperture of a front aiming sight to align visually with a rear sighting aperture of a rear aiming sight. When aiming, the specific target point is viewed in the voids of the front sighting aperture and the rear sighting aperture without obstruction.
