EOTech  Holographic  Weapon  Sight  HWS  557.AR223  has been developed to optimize the functionality of the EOTech HWS. The buttons have been moved from the back to the left side for instant access, allowing a magnifier, night vision, or a back-up iron sight to fit closely to the EOTech HWS body. This button position allows the user to operate the EOTech HWS function switches easier than ever before. It also allows for NV devices and magnifiers to be mounted right behind the HWS without interfering with access to the brightness controls. 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 L3 EOTech 557.AR223 Holographic Weapon Sight is configured with a new ballistic matching reticle image for the M4 carbine. The battle tested circle/dot reticle is offered along with a series of 1 MOA aiming dots that are vertically aligned and calibrated specifically for the ballistic drop of .223 cal.
