ABSTRACT:
A gun sight comprises a block of transparent material having a line of sight therethrough between a target end and a viewing end. A graticule pattern is mounted to the, in use, top surface of the sight whereby it may be illuminated by light from the sky generally above the sight. The block has a first internally reflecting surface disposed below the graticule pattern and aligned to reflect light therefrom to a second reflecting surface, which in turn is aligned to reflect light from the graticule to a partially reflective doublet lens system in the line of sight. The partially reflective doublet pattern reflects said doubly reflected light to form a virtual image of the graticule at infinity in the line of sight.
