Abstract

An illuminable laser sight has a power source, a laser module coupled to the power source, a laser module coupled to the power source and having a laser diode for emitting laser beams, and an adjuster module positioned around the laser module and coupled to the power source, the adjuster module having a front face and a laser light exit formed at the center of the front face and aligned with the laser diode. The laser sight further includes an illuminator module positioned adjacent the front face of the adjuster module, the illuminator module having a plurality of LEDs arranged in an annular manner to define a central bore that is axially aligned with the laser light exit and the laser diode.

Claims
