Gun sight flashlight adapter

Abstract

A gun sight flashlight adapter and improvement thereof, includes an upper sight portion with a sight post disposed between two sight guards and a middle sight portion adjacent to the upper sight portion, the middle sight portion defining an aperture having a diameter that is at least two hundred percent larger than the height of the sight post. The gun sight flashlight adapter also having a lower sight portion adjacent to the middle sight portion shaped to mechanically couple the gun sight flashlight adapter with a firearm.

1 . A gun sight flashlight adapter comprising:
 a body defining:
 an upper target alignment portion including a sight post; 
 a coupling portion shaped to mechanically couple the body to a firearm; and 
 an aperture positioned between the upper target alignment portion and the coupling portion, wherein the aperture is shaped to accept a light-output portion of a flashlight. 
   
     
     
         2 . The gun sight flashlight adapter according to  claim 1 , wherein:
 the aperture is sized to allow more than approximately 85% of a light output from the flashlight to pass therethrough.   
     
     
         3 . The gun sight flashlight adapter according to  claim 1 , wherein:
 the aperture is sized to allow sufficient light generated by the flashlight to pass through and illuminate at least 10% of a human-sized target at least 10 feet from the battery-powered light source.   
     
     
         4 . The gun sight flashlight adapter according to  claim 1 , further comprising:
 a first sight-post protector member at the upper target alignment portion and a second sight-post protector member at the upper target alignment portion, wherein the sight post is positioned between the first sight-post protector member and the second sight-post protector member.   
     
     
         5 . The gun sight flashlight adapter according to  claim 1 , wherein:
 the coupling portion is shaped to mechanically couple to a hand guard of the firearm.   
     
     
         6 . The gun sight flashlight adapter according to  claim 5 , wherein:
 the mechanical coupling between the coupling portion and the hand guard is a slidable engagement.   
     
     
         7 . A gun sight flashlight adapter comprising:
 an upper sight portion including a sight post;   a lower sight portion shaped to mechanically couple the gun sight flashlight adapter to a firearm; and   a middle sight portion disposed between the upper sight portion and the lower sight portion, the middle sight portion defining an aperture, the aperture:
 transmitting light output from a battery-powered light source; and 
 having a diameter that is at least 200% larger than a height of the sight post. 
   
     
     
         8 . The gun sight flashlight adapter according to  claim 7 , wherein the upper sight portion comprises:
 a left sight guard and a right sight guard having the sight post disposed between the left and right sight guards.   
     
     
         9 . The gun sight flashlight adapter according to  claim 7 , wherein:
 the aperture transmits more than approximately 85% of the light output from the battery-powered light source.   
     
     
         10 . The gun sight flashlight adapter according to  claim 7 , wherein:
 the aperture transmits sufficient light generated by the battery-powered light source to pass through and illuminate at least 10% of a human-sized target at least 10 feet from the battery-powered light source.   
     
     
         11 . The gun sight flashlight adapter according to  claim 7 , wherein:
 the lower sight portion is shaped to mechanically couple to a hand guard of the firearm.   
     
     
         12 . The gun sight flashlight adapter according to  claim 11 , wherein:
 the mechanical coupling between the lower sight portion and the hand guard is a slidable engagement.   
     
     
         13 . The gun sight flashlight adapter according to  claim 7 , wherein:
 the lower sight portion is shaped to mechanically couple to a barrel of the firearm.   
     
     
         14 . In combination with a rifle assembly comprising a barrel, a hand guard surrounding at least a portion of the barrel, and a battery-powered light source coupled to the hand guard, the improvement comprising:
 a gun sight flashlight adapter including:
 a first sight portion including:
 a left sight guard; 
 a right sight guard; and 
 a sight post disposed between the left sight guard and the right sight guard; and 
 
 a second sight portion disposed adjacent the first sight portion and defining an aperture shaped to receive at least a portion of the battery-powered light source. 
   
     
     
         15 . The combination of  claim 14 , further comprising:
 a third sight portion shaped to mechanically couple the gun sight flashlight adapter to a firearm.   
     
     
         16 . The combination of  claim 14 , wherein:
 the aperture is sized to allow more than approximately 85% of a light output from the battery-powered light source to pass therethrough.   
     
     
         17 . The combination of  claim 14 , wherein:
 the aperture is sized to allow sufficient light generated by the battery-powered light source to pass through and illuminate at least 10% of a human-sized target at least 10 feet from the battery-powered light source.   
     
     
         18 . The combination of  claim 14 , wherein:
 the third sight portion is shaped to mechanically couple to a hand guard of the firearm.   
     
     
         19 . The combination of  claim 18 , wherein:
 the mechanical coupling between the third sight portion and the hand guard is a slidable engagement.
