Sighting system for firearms

Abstract

A sighting apparatus for firearms is disclosed. The sighting apparatus for a firearm includes a front sight and a rear sight. The front sight includes a body having a top edge, a left edge and a right edge. An opening is located between the left and right edges of the body, and the opening is also open to the top edge of the body. The front sight includes a first and second projections to provide a point of aim for the front sight, and the point of aim is located in the middle of an imaginary line extended between a point of the first projection and a point of the second projections. The front sight also includes a ring with its center concentric with the point of aim. The front sight can be attached to a firearm at a base of the body. The rear sight includes a body having a set of apertures of various sizes.

What is claimed is: 
     
         1 . A sighting apparatus comprising:
 a front sight includes
 a body having a top edge, a left edge and a right edge; 
 an opening within said body, wherein said opening is located between said left and right edges of said body, wherein said opening is also open to said top edge of said body; 
 a first projection and a second projection to provide a point of aim for said front sight, wherein said first and second projections are located at said top edge of said body, wherein said first and second projections are formed by said opening and said top edge of said body, wherein said point of aim for said front sight is located in the middle of an imaginary line extended between said first and second projections; 
 a base for attaching said body to a firearm; and 
 a ring affixed to said front sight with its center concentric with said point of aim; and 
   a rear sight includes a body having a plurality of apertures of various sizes.   
     
     
         2 . The apparatus of  claim 1 , wherein said opening is located in the middle of said left and right edges of said body. 
     
     
         3 . The apparatus of  claim 1 , wherein said opening is in an inverted key shape. 
     
     
         4 . The apparatus of  claim 1 , wherein said rear sight includes a primary aperture and a plurality of secondary apertures located within an imaginary circle. 
     
     
         5 . The apparatus of  claim 4 , wherein said primary aperture is located below said plurality of secondary apertures. 
     
     
         6 . The apparatus of  claim 4 , wherein said primary aperture is located above said plurality of secondary apertures. 
     
     
         7 . The apparatus of  claim 1 , wherein said body includes a first tritium lamp located between said first projection and said first edge, and a second tritium lamp located between said second projection and said second edge. 
     
     
         8 . The apparatus of  claim 1 , wherein a gap between said first and second projections provides a local two-axis symmetry for making said front sight insensitive to focus for its function as an accurate aligning device, and allows a user to focus on a target instead of said front sight.
