In holography, all the information required to reconstruct the reticle image is recorded everywhere in the Heads-up-Display window. If the window is obstructed by mud, snow, rain, etc. the UWS remains fully operational with point of aim/impact being maintained. Even in such extreme cases where the front window is shattered, the HWS is fully functional and the zero is maintained! As long as the operator can see through any portion of the window, the entire reticle pattern is visible on target. The operator can still engage with confidence. The 517.A65 was developed to optimize the functionality of the HWS. The buttons have been moved from the back to the left side for instant access, allowing a magnifier or a back up iron sight to fit closely to the HWS body. This new button position allows the user to operate the HWS function switches easier than ever before. Additionally, a portion of the front base has been raised to allow the sight to fit over standard hand guards found on many M-4 or M-16 style weapons. Does not have night vision compatibility. Battery Life is 1,000 continuous hours (lithium) at normal setting 12;600 continuous with AA alkaline.
