ABSTRACT:
An adjustable rear gun sight includes a rear sight fixed base for rigid attachment to a gun, and an elongated rear sight movable base disposed in longitudinal alignment with the fixed base. The movable base has a rearwardly disposed sight blade for helping to sight the weapon. A cam device, having a manually rotatable member, is mounted on the fixed base for retaining releasably the bases in a given longitudinal alignment relative to one another. The fixed base is journalled for enabling the manually rotatable member to rotate about a fixed axis of rotation. The cam device has an eccentrically located member which engages the movable base to drive the movable base in a reciprocative path of travel relative to a fixed axis of rotation so that the bases can be moved relative to one another into an adjusted position, and maintained releasably thereat.
