SureFire developed the first laser sight for firearms and that legacy carries forward with today's SureFire laser sights. The laser-sights can be mounted either in conjunction with a SureFire WeaponLight or as a separate unit. SureFire lasers use continuous-beam operation to provide about twice the average power of typical pulsing lasers. This translates to a brighter constant beam that is much easier to follow when tracking a target.
