New version of the ACM 552 Holosight (HWS) which is offered by Tactical Gear Depot... "The HWS employs a true Heads-Up Display that eliminates blind spots, constricted vision, or the tunnel vision associated with tubed sights. All user controls are flush to the HWS's streamline housing with no protruding knobs, battery compartments or mounting rings blocking vision at the target area. True, 2 eyes open shooting is realized. Instant threat identification is achieved by maximizing the operator's peripheral vision and ultimately gaining greater control of the engagement zone.
