Integral telescopic sight for firearms

Abstract

A unified firearm and optical sight integrates the mounting of the optical elements directly into a one-piece frame, receiver, or barrel of the firearm. This solves some technical limitations caused by keeping the firearm and the telescopic sight as separate products. Merging the optics into the frame of the firearm reduces the distance between the optical elements and the barrel, which reduces parallax error. Reducing the number of mechanical connections between the optical elements and the barrel improves the rigidity of the connection, which reduces point-of-aim errors from bumps and shocks. Integrating the telescopic sight into the firearm makes for a smaller and smoother package, which makes it possible for the firearm to be carried in a concealed way. This invention applies to all types of firearms, including handguns, pistols, revolvers, rifles, shotguns, NFA firearms, and AOW firearms.

1 . A handgun comprising:
 a unitary handgun frame;   the frame having an internal elongated cavity; and   an optical sight comprising multiple refractive elements, the optical sight retained within the cavity.   
     
     
         2 . A handgun, according to  claim 1 , and wherein:
 a handgun frame has a forward end and an rear end; and   the cavity extends from the forward end to the rear end.
