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

• Speed of Target Acquisition and Engagement - As quickly as the shooter can pick up the target, they can engage with cinfidence. The horizontal and vertical reference lines naturally center and level the reticle in the window to allow for fast target acquisition.
• Achieve First Round on Target - Get you first round on target instead of having to walk in your shot. Eliminate the target faster, with less collateral damage and less wasted ammunition.
• Can handle the abuse - Can take the massive force recoil of the .50 cal BMG round. Can even handle the high cyclic rate of the M2 machine gun without fail.
• Simple to Use by all Levels of Operators - Simply put the dot on the target and pull the trigger.
