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.

Abstract: An automatically recyclable burst control mechanism for weapon systems wh is responsive to trigger action to actuate automatic recycling of the burst control mechanism to its initial position, independent of the number of rounds fired in each preceding automatic burst.
