Side view of a Feinwerkbau LG700 rear sight
This is the rear sight used in the photograph of the marksman's eye view of the target. The marksman looks through the sight from left to right and the eyepiece is so close to the eye that no detail of it can be made out. The eyepiece is used to centralise the eye with the foresight and to adjust the amount of light by varying the aperture (blue ring) and the colour of the view (ring with coloured marks). Elevation and lateral movements are adjusted by means of the two white knobs. Although this sight is from an air rifle, very similar ones are used for precision .22 rimfire and larger calibre centrefire precision target shooting at all distances, both indoors and on open air ranges.
