Patent ID: 7726061

Claim:
A dual beam laser aiming module for a firearm comprising: a dual-laser alignment housing having a first cavity and a second cavity formed therein; a first laser assembly that is fixed in the first cavity and that has a first beam axis; a second laser assembly that has a second beam axis and that is adjustably located in the second cavity to provide the second beam axis substantially parallel to the first beam axis; a laser housing adapted to be fixed to the firearm and having a cavity formed therein for receiving the dual-laser alignment housing, wherein 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; and an adjustment mechanism for adjustably pivoting the dual-laser alignment housing with respect to the laser housing to align the substantially parallel first and second axes further substantially parallel to a centerline of a barrel of the firearm, the adjustment mechanism for adjustably pivoting the dual-laser alignment housing with respect to the laser housing comprising a four-point laser alignment mechanism for adjustably pivoting the dual-laser alignment housing with respect to the laser housing to align the substantially parallel first and second axes substantially parallel to the centerline of the barrel of the firearm, wherein the four-point laser alignment mechanism includes: a first adjustment screw, an end of which contacts the dual-laser alignment housing and which is aligned for movement in a first direction, the first direction being substantially perpendicular to the centerline of the barrel; a second adjustment screw, an end of which contacts the dual-laser alignment housing and which is aligned for movement in a second direction, the second direction being substantially perpendicular to the centerline of the barrel and substantially orthogonal to the first direction of the first adjustment screw; and two spring-loaded bushings that bias the dual-laser alignment housing against a respective end of the first and the second adjustment screws.
