A front bow sight may include a housing, one or more primary pins having sighting tips within an opening through the housing, and a drop pin extending below the housing and providing a long range sighting tip below the housing.

An optical aiming scope mount (10) includes a base (12) configured to attach to a weapon system. At least two longitudinally spaced apart scope mounting rings (14, 16) are on the base. A first chamber (34) is formed in a portion of the base (12). A plurality of electrical connectors (38) on the base (12) are operatively joined by a circuit (46) at least partially located in the first chamber (34) to provide a power/data distribution bus.

An electronic indicator on a see-through optical scope indicates whether an optical system is canted. The indicator may include illuminable visual indicators positioned on opposite sides of a field of view through the optical scope. The indicator may be visual, haptic, or aural. The visual indicator may include one or more LEDs positioned on the periphery of the field of view, and may be optically coupled to an appropriate position on the face of the reticle using a suitable waveguide. The LEDs are coupled to a microprocessor which is, in turn, coupled to a solid-state electronic inclinometer that is incorporated into the internal structure of the optical system. The microprocessor is configured to selectively illuminate one or more of the visual indicators based on the output of the inclinometer, thereby indicating how the reticle is canted, if at all.

A level indicator system for an aiming system comprising a base assembly, a level assembly. The base assembly comprises a base member defining a base axis, a plate, and a support member. The level assembly comprises a level indicator defining a level axis. The base member and the plate support the support member such that a location of the plate relative to the base member is adjustable. The support member supports the level assembly such that a location of the level axis relative to the base axis is altered when a location of the plate relative to the base member is adjusted.

A cant indication apparatus includes a spirit level, at least one light receiving optical fiber, and at least one light transmitting and cant indicating optical fiber. The spirit level includes a first fluid with at least one of a first light transmittance or absorbance, and a second fluid with at least one of a second light transmittance or absorbance. A position of a bubble formed by the second fluid in the first fluid indicates at least an uncanted orientation and a canted orientation. The at least one light receiving optical fiber includes a light receiving end, and a spirit level connection end proximate to the spirit level. The at least one light transmitting and cant indicating optical fiber includes a spirit level connection end proximate to the spirit level, and an orientation indication end. Illumination through the orientation indication end indicates the bubble is in the uncanted orientation.

In one aspect, a sighting device for a weapon includes an orientation sensor configured to detect a weapon cant, a display having one or more visual indicators, and a processor. The processor is configured to receive information regarding weapon cant from the orientation sensor and is further configured to control the one or more visual indicators of the display output to provide a visual indication of excessive weapon cant. In a further aspect, a method of sighting a target is provided.
