Firearm Mount with Embedded Laser Sight

Abstract

A laser sight is embedded in a mounting rail otherwise used for attaching accessories to small arms discharge devices such as pistols or rifles. The mounting rail has a transverse profile that extends along an axis of the mounting rail for engaging mating features of the accessories. The laser sight is located at least partly within the transverse profile of the mounting rail and has a sighting axis that extends substantially parallel to the axis of the mounting rail.
