The new 557.AR223 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 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 557.AR223 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.
