The EOTech 557.AR223 features a ballistic reticle specific to .223 caliber munitions.
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.
Buttons on left side to work specifically with NV or magnifiers
AA Battery model (supports Lithium or Alkaline)
Ballistic reticle specific to .223 caliber munitions
Compatible with Gen I-IV Night Vision Systems (tandem operation)
Raised 7mm base
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 HWS remains fully operational , with point of aim/impact being maintained. Even in such extreme cases where the laminated window is shattered, the HWS is fully functional! 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.
