Magnetic lightweight collimator

Abstract

An optical collimator device for use in aligning a gun bore with a gun sight is formed of a graticule and lens which are located within the optical collimator device housing. The optical collimator device is mounted on the end of the gun barrel with a magnetic bar and rail structure formed in the optical collimator device housing and this magnetic bar and rail structure allows the optical collimator device to adjust vertically for use with guns with low sights and with raised sights and large bore diameters such as shotguns and baton guns

We claim:  
     
         1 . An optical collimator device for aligning a bore and a sight of a gun comprising: 
 a reticule mounted in a housing for use in aligning a sight and a bore of a gun;    a lens mounted in relation to said housing for viewing said reticule, said reticule and said lens forming an optical collimator; and    a magnetic bar for mounting said optical collimator to a barrel of said gun, wherein said magnetic bar enables said optical collimator to adjust vertically relative to said barrel.    
     
     
         2 . The optical collimator device of  claim 1 , wherein said housing is formed of a plastic material.  
     
     
         3 . The optical collimator device of  claim 1 , wherein said lens is a magnifying optic.  
     
     
         4 . The optical collimator device of  claim 1 , wherein said lens is plastic.  
     
     
         5 . The optical collimator device of  claim 1 , wherein said lens is an aspherical lens.  
     
     
         6 . The optical collimator device of  claim 1 , further including a plurality of rails adjacent to said magnetic bar for aiding the alignment of said device.  
     
     
         7 . The optical collimator device of  claim 6 , wherein said rails are steel rails.  
     
     
         8 . A method of aligning a barrel and a sight of a gun comprising the steps of: 
 magnetically mounting an optical collimator device on a muzzle of said barrel, wherein said optical collimator device is comprised of a reticule for use in aligning said sight and said barrel, a lens for viewing said reticule, and a magnetic bar for mounting said optical collimator device to said gun,    adjusting said optical collimator device vertically relative to said barrel until said optical collimator device is the correct vertical height for said sight; and    adjusting said sight so that it points to a correct point on said reticule thereby aligning said sight with said barrel of said gun.    
     
     
         9 . The method of  claim 8 , wherein said sight is a low iron sight.  
     
     
         10 . The method of  claim 8 , wherein said sight is a raised gun sight.  
     
     
         11 . The method of  claim 8 , wherein said raised gun sight is a telescopic magnifying sight.  
     
     
         12 . The method of  claim 8 , wherein said raised gun sight is an electronic red dot sight.  
     
     
         13 . The method of  claim 8 , wherein said gun is a rifle.  
     
     
         14 . The method of  claim 8 , wherein said gun is a hand gun.  
     
     
         15 . The method of  claim 8 , wherein said barrel of said gun is stainless steel.
