A reticle for an optical gun sight is provided having a plurality of vertical reference lines which extend below a horizontal reference line. The grid pattern of vertical reference lines and horizontal reference lines further provide a pattern of at least five vertical lines which extend below a horizontal reference line to a left side of a vertical center line and a second pattern of at least five reference lines which extend below the horizontal reference line and to a right of a vertical center line.

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.

A sight system for a firearm may comprise a corrective sight. The corrective sight may be disposed adjacent a first end of a barrel of the firearm. The corrective lens may comprise an aiming tool, such as a reticle lens. The sight system may comprise a front sight disposed adjacent a second end of the barrel of the firearm. The corrective sight may comprise an optical lens with a positive optical power. The positive optical power may be configured to provide substantially clear vision of at least one of a target, the aiming tool, an indicia of the aiming tool, or the front sight when viewed through the optical lens. The sight system may comprise a retaining body configured to house at least a portion of the corrective sight. The sight system may comprise a mounting element configured to mount the corrective sight the firearm. The sight system may comprise the firearm.

A rear-sight aiming device to aid a shooter of a firearm. The device includes a housing with a tunnel alignable with the front aiming sight; an elongated optical fiber in a non-linear configuration is disposed inboard within the tunnel; an annular light-transmitting cylinder, disposed within the tunnel between the optical fiber and the shooter of the firearm during shooting; and a self-activating light source coaxially and completely disposed within the cylinder.

An auxiliary optical system is installed on a telescopic sight of a gun, the telescope sight including an eyepiece end, an objective end and a first reticle. The system includes a digital imaging member fixed at the objective end by a first fixing member and partially shielding an objective lens, a display member fixed at the eyepiece end by a second fixing member and electrically connected to the digital imaging member; the digital imaging member configured to perform photosensitive image on environmental images and convert the environmental images into video signals, and generates a second reticle that is adjustable and has the same function as the first reticle, the second reticle and the video signals stacked together to be transmitted to the display member for display. The present disclosure enables the gun to have functions of the digital sight without replacing a conventional telescopic sight.

A gunsight system for aiming a firearm is disclosed. The gunsight system includes a front sight and a rear sight. The firearm has a barrel defining a bore that extends along a gun bore axis. The gun bore axis extends in a forward direction and a rearward direction. The front sight comprises a front sight post including a front sighting element. The rear sight comprises a rear sight post including a rear sighting element. Each sight post is pivotable between a deployed position and a reclined position. When the sight post are in the deployed position, the user may aim the firearm with reference to a sight line extending through the front and rear sighting elements. The sight line and the gun bore axis may be generally parallel to one another when the sight arms are in the deployed position.
