Abstract: Embodiments herein relate to the field of firearms, and, more specifically, to laser sights for firearms, particularly laser sights having multiple laser diodes. Various embodiments of the disclosed systems may include two or more lasers in a single unit, and may not only be relatively less expensive relative to units with two separate lasers and housings, but they may also be easier to calibrate and use. For example, in various embodiments, the system may include two or more lasers that may be adjusted for windage and elevation (e.g., calibrated) simultaneously. Thus, in various embodiments, one or more infrared diodes may be calibrated automatically when a corresponding visible light diode is calibrated, and vice versa.
