This invention discloses a riflescope wherein the point of aim is adjusted by a pair of partially-rotating wedge prisms. The prisms are positioned in front of the objective lens of the riflescope. The deviation axes of the prisms are oriented perpendicular to each other such that one deviates the light beam in the horizontal direction and the other in the vertical direction. It is shown, using the geometric properties of a tangent to a circle, that rotating each prism by a small amount can produce an approximately linear shift in the point of aim of the riflescope. The riflescope introduced in this invention has no laterally-moving parts, no turrets and no off-axis optical components. Therefore, it provides a very robust and reliable point of aim. Additionally, the riflescope has a streamlined body which is aesthetically pleasing and easier to mount on the long receiver of magnum hunting rifles.

Optical sights for mounting on a firearm are provided, each of the sights having a base defining a barrel end and a rear end; a frame extending upwardly from the base at the barrel end and defining an opening; an optical element received in the opening; and an illumination device operable to display an aiming point on the optical element to generate said aiming point.

A firearm illuminator has a housing having a front portion, a rear portion, and an intermediate portion between the front and rear positions, a light source at the front portion, a power source at the rear portion, a power conductor interconnecting the light source and the power source and coextensive with the intermediate portion, and a weapon sight connected at the intermediate portion between the light source and the power source. the weapon sight may be a post sight. The weapon sight may be a front sight configured to register with a rear weapon sight. The weapon sight may be movable between a stowed position and an extended position. An indicating portion of the weapon sight extends above the housing when in the extended position. The housing may have an upper surface below a selected limit level. The weapon sight may be configured to extend above the limit level.

In one example, the disclosure relates to adjustable flip up sight assembly that can be adjusted vertically and laterally in particular, for an automatic firearm, comprising a front sight support element that is supported by an axle on a mount, in particular such that they can pivot thereon, wherein the front sight support element has an adjustment element supported on a spring element and releasably connected to a front sight, which contains a keyhole type opening through which the axle is inserted, wherein the adjustment element can be moved in relation to the axle against the spring force between two positions inside the front sight support element such that the keyhole opening prevents a lateral movement of the front sight support element along the axle when engaged with the axle, and allows the lateral adjustment of the front sight support element in a released position.

The current system is a method for easily adjusting the front sight post on a firearm. The system is used to aid in easier front sight post adjustments as well as maintain a uniform sight picture throughout the aiming process. The system solves the current problem of viewing two separate sight pictures when looking through a rear sight. The system also solves the problem of needing a separate tool to adjust the sight post. The system includes four critical parts, a bottom sight post tower, a top sight post tower, a front sight post and a mechanism for providing constant upward force such as a spring. The system has multiple embodiments including the use of various sight posts.

A firearm includes an integrated rail and sight system that slidably mounts to the top of the firearm and is also retractable and detachable from the firearm. The rail may slide on and off the top of the firearm and may include integrated front and rear flip down sights. Both sights are pinned to the rail and can fold down to the rail such that they are flush with or seat below the top portion of the rail. This permits accessories to be mounted to the rail without the sights interfering with the mounting of the accessories or without the sights interfering with the operation of the accessories. The firearm further includes an ambidextrous charging handle mounted through the integrated rail and sight system.
