DESC:Technical Field of the Invention

[0001] The present invention relates to a laser bore sighting system and method for aligning sights to firearms.

Background of the Invention

[0002] Conventional systems provide sights for aiming firearms such as rifles and pistols. It is well known that the line of sight between shooter and target is a straight line. The high-powered scopes are considered for accuracy of a rifle at most of the ranges. The scope is mounted on the top of the rifle or pistol and provides a magnified view of the potential target when sighted.

[0003] It is necessary to adjust the sights of the firearm at an angle with the bore of the barrel of the gun or firearm where the angle is determined by the distance from the muzzle of the firearm to the target and the trajectory of bullet. When the firearm sight is adjusted properly, the projectile from the firearm will strike the target at position identified through visual alignment with a feature of the scope such as intersection of scope cross-hairs. However, the adjustment of the scope can be made to align the cross hairs of the scope with the actual point at which the round of ammunition struck the target may take several iterations and is less precise. Another drawback of conventional systems are sighting the target is not accurate and leads to more wastage of time.

[0004] To overcome the aforesaid disadvantages, there is a need to develop a laser bore sighting system and method for aligning sights to firearms.

[0023] In accordance with the exemplary embodiment of present invention, the position of camera housing unit and the laser source is adjusted by adjusting unit to achieve uniform intensity of circular laser beam.

[0024] In accordance with the exemplary embodiment of present invention, the system characterized to be used to align sights to firearms to improve the hit probability.

[0025] In accordance with the exemplary embodiment of present invention, a method for calibrating a bore sighting system is disclosed. The method comprising steps of affixing a laser source and a cone mirror to form a circular laser beam in the bore, arranging a camera housing unit with at least two cameras concentrically, configuring the cameras for observing the circular laser beam and a target and providing an adjusting unit to adjust the system into coordinate axes.

[0026] In accordance with the exemplary embodiment of present invention, the cameras are concentrically aligned on the observing unit and connected with laser source and cone mirror.

[0029] Fig. 1 illustrates a cross sectional view (100) depicting a laser bore sighting system placed inside the barrel of the firearm according to the present invention. The system is used for accurately sighting a target when using a firearm having a bore so as to improve hit probability of the firearm. The laser bore sighting system comprises a laser source (102), a camera unit (104) containing two cameras camera 1 (106) and camera 2 (108), cone mirror (114) and an adjusting unit (110).
