Precise Measured Glass Coated Lens Pro Red Dot Laser Alignment
Unlike the use of any prior dot positioning work, in order to make precise and clear dot indication at various work distances, it enables high precision dot measurement with a pro red dot laser alignment. Employed by an import 635nm red laser diode and cooling system inside a different dimension metal housing tube, it gets larger space leaving for tube cooling down, easy carrying and long time lasting red dot projection in proper use.
