Abstract
A dual beam laser aiming module for a firearm has a dual-laser alignment housing with a first IR laser assembly in a first cavity and that provides a first beam axis. A second visible laser assembly is adjustably located in a second cavity to provide a second beam having an axis parallel to the first beam axis. A housing for the dual-laser alignment housing is adapted to be fixed to the firearm. The dual-laser alignment housing has a rounded exterior surface that interfaces with a corresponding rounded surface in the interior of the cavity of the laser housing. The dual-laser alignment housing is adjustably pivoted with respect to the laser housing with a four-point laser alignment mechanism to align the parallel first and second axes further in parallel to a centerline of a barrel of the firearm.
