ABSTRACT:
A rear gunsight has a rectangular-shaped base member, with a left sidewall extending upwardly from a left hand side of the base member and a right sidewall extending upwardly from a right hand side of the base member. A left hand top element extends from an upper end of the left sidewall toward the right sidewall, and a right hand top element extends from an upper end of the right sidewall toward the left sidewall. The base, the sidewalls and the top elements enclose a hollow space that is open at a front end and a rear end of the gunsight so that one can see through the hollow space. A notch is formed between the terminal ends of the right and left hand top elements, and the notch opens into the hollow space as well as being open at its opposite ends so that one can see through the notch simultaneously with seeing through the hollow space. A boss extends upwardly into the hollow space from the planar upper surface of the base member, with the boss being positioned centrally between the left and right sidewalls so that two spaced apart sight chambers are formed on opposite sides of the boss. The boss has a flat upper surface that is spaced from the left and right hand top elements so that an open passage is formed between the notch and each of the sight chambers.
