The new EOTECH 517 MILITARY AA .223 BLK has been 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.
The EOTECH 517 MILITARY AA .223 BLK is nearly identical to the 512 sight with two important differences. First, the control buttons are placed on the side of the sight, allowing you to more naturally make adjustments while keeping your rifle shouldered. The side control buttons also make using the sight easier when combined with magnifiers or other accessories. Secondly, a portion of the front of the base of the EOTech 517 sits 7 millimeters higher, permitting you to attach the sight over the hand guard of M4 and AR15/M16 rifles.
The EOTech 517 HOLOgraphic weapon sight also includes twenty different brightness levels that ensure proper brightness control in either low light or very bright sunlight. An on-board microprocessor provides automatic battery check indicator, up/down brightness scrolling and programmable auto shutdown features. All electronics on the EOTECH 517 MILITARY AA .223 BLK are fully encapsulated in a shock absorbing resin compound.
