ABSTRACT:
A sighting structure for a weapon such as a rifle, which can hold its alignment to precision, despite repeated recoil of the weapon, is disclosed. The sighting structure is suspended in an elastomer, within a housing, and the sight alignment can be adjusted from outside the housing over two planes by vertical and horizontal set screws. The housing also serves to protect what might be a delicate instrument sight from the elements, by the possibility of enclosing it within the housing, and also providing transparent or opaque end pieces for the housing.
