Externally adjustable gun sight

Abstract

An adjustable holographic gun sight has a base and a carrier pivotally connected to the base. An adjustment mechanism may be adapted to pivot the carrier with respect to the base. A pair of dropouts connects the carrier to the base and the dropouts allow the carrier to pivot with respect to the base. The dropouts may be mounted to an external portion of the carrier and the base thereby provides for external adjustment of the gun sight.
