ABSTRACT:
A gun sight positioning mechanism includes a slip clutch coupled sight slide that enables gun sight optics to be adjusted to extended firing ranges independently of gun inclination; a first range indicator fixed on the gun sight is associated with the sight slide to indicate the "range of target" and coincident adjustment of gun sight optics and a second range indicator is movably fixed to a gun elevating trunnion to serve as a memory of gun inclination so that a gunner will be able to remember to move (if required) the gun following manipulation of the sight slide to a different "range of target" position.
