Product Info for EOTech 557 AR223 Holographic Sight

EOTech 557.AR223 Sight 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, night vision, or a back up iron sight to fit closely to the holographic weapon sight 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 weapon sight to fit over standard hand guards found on many M-4 or M-16 style weapons.image

The 557.AR223 by L-3 EOTech is configured with a new ballistic matching reticle image for the M4 carbine. The battle tested circle/dot reticle will be offered along with a series of 1 MOA aiming dots that are vertically aligned and calibrated specifically for the ballistic drop of .223 caliber ammunition. The reticle provides 4 aiming dots for target distances of 0-300m, 400m, 500m, and 600m. The use of a magnifier is strongly recommended with this EOTech optical sight.
