Abstract

An optical aiming device that includes front and rear mounting rings having protrusions configured to engage grooves in a cylindrical body for alignment of the optical aiming device.

The invention claimed is: 
     
         1 . An optical aiming device comprising:
 front and rear mounting rings;   one or more protrusions positioned on an inner surface of the front and rear mounting rings; and   a cylindrical body having longitudinal axis and one or more grooves parallel to the longitudinal axis in a surface of the cylindrical body being configured to couple with the one or more protrusions to provide accurate positioning of a crosshair or aiming point (reticle) in the optical aiming device.   
     
     
         2 . The optical aiming device of  claim 1 , wherein the front and rear mounting rings include semicircular shaped top and bottom sections sized to clamp the cylindrical body when joined. 
     
     
         3 . The optical aiming device of  claim 2 , wherein the top and bottom sections include outward extending upper and lower mating tabs or flanges include screw holes, wherein screws are inserted through the screw holes in the upper mating tabs and engage either threaded screw holes in the lower mating tabs or pass through screw holes in the lower mating tab and couple with nuts to join the upper and lower mating tabs or flanges. 
     
     
         4 . The optical aiming device of  claim 2 , wherein the one or more protrusions positioned on an inner surface of the bottom section. 
     
     
         5 . The optical aiming device of  claim 4 , wherein the one or more protrusions are detachable protrusions, and the bottom sections include one or more slots configured to receive the one or more detachable protrusions. 
     
     
         6 . The optical aiming device of  claim 1 , wherein the one or more protrusions are a triangular shape and the grooves are triangular grooves. 
     
     
         7 . The optical aiming device of  claim 1 , wherein the one or more protrusions are a rectangular shape and the grooves are rectangular grooves. 
     
     
         8 . The optical aiming device of  claim 1 , wherein the cylindrical body includes a front set of grooves configured to couple with protrusions of the front mounting ring and a rear set of grooves configured to couple with protrusions of the rear mounting ring. 
     
     
         9 . The optical aiming device of  claim 8 , wherein the cylindrical body the front set of grooves are different than the rear set of grooves so that when the cylindrical body is coupled with the front and rear mounting rings it is positioned in the correct orientation on the firearm. 
     
     
         10 . An optical aiming device comprising:
 front and rear mounting rings having semicircular shaped top and bottom sections;   one or more protrusions positioned on an inner surface of the front and/or rear mounting rings; and   a cylindrical body having longitudinal axis and one or more grooves in a surface of the cylindrical body parallel to the longitudinal axis being configured to couple with the top and bottom sections to provide accurate positioning of a crosshair or aiming point (reticle) in the optical aiming device.   
     
     
         11 . The optical aiming device of  claim 10 , wherein the top and bottom sections include outward extending upper and lower mating tabs or flanges include screw holes, wherein screws are inserted through the screw holes in the upper mating tabs and engage either threaded screw holes in the lower mating tabs or pass through screw holes in the lower mating tab and couple with nuts to join the upper and lower mating tabs or flanges. 
     
     
         12 . The optical aiming device of  claim 10 , wherein the one or more protrusions are detachable protrusions, and the bottom sections include one or more slots configured to receive the one or more detachable protrusions. 
     
     
         13 . The optical aiming device of  claim 10 , wherein the cylindrical body includes a front set of grooves configured to couple with protrusions of the front mounting ring and a rear set of grooves configured to couple with protrusions of the rear mounting ring. 
     
     
         14 . The optical aiming device of  claim 13 , wherein the cylindrical body the front set of grooves are different than the rear set of grooves so that when the cylindrical body is coupled with the front and rear mounting rings it is positioned in the correct orientation on the firearm. 
     
     
         15 . An optical aiming device comprising:
 front and rear mounting rings having semicircular shaped top and bottom sections outward extending upper and lower mating tabs or flanges having screw holes;   one or more protrusions positioned on an inner surface of the front and rear mounting rings; and   a cylindrical body having longitudinal axis and one or more grooves in a surface of the cylindrical body parallel to the longitudinal axis being configured to couple with the top and bottom sections to provide accurate positioning of a crosshair or aiming point (reticle) in the optical aiming device.   
     
     
         16 . The optical aiming device of  claim 15 , wherein the upper and lower mating tabs or flanges include screw holes and screws are inserted through the screw holes in the upper mating tabs and engage either threaded screw holes in the lower mating tabs or pass through screw holes in the lower mating tab and couple with nuts to join the upper and lower mating tabs or flanges. 
     
     
         17 . The optical aiming device of  claim 15 , wherein the one or more protrusions are detachable protrusions, and the bottom sections include one or more slots configured to receive the one or more detachable protrusions. 
     
     
         18 . The optical aiming device of  claim 15 , wherein the cylindrical body includes a front set of grooves configured to couple with protrusions of the front mounting ring and a rear set of grooves configured to couple with protrusions of the rear mounting ring. 
     
     
         19 . The optical aiming device of  claim 18 , wherein the cylindrical body the front set of grooves are different than the rear set of grooves so that when the cylindrical body is coupled with the front and rear mounting rings it is positioned in the correct orientation on the firearm.
