This kit places the AT3 ACE at a lower 1/3 co-witness height on AR-15s equipped with standard-height iron sights. The raised sight line keeps the irons in the lower portion of the optic window while leaving a less obstructed view through the ACE. Red and green 3 MOA reticle options are available.
Note: Co-witness position is based on standard-height AR iron sights and may vary slightly with the firearm and sight models used. Only use the included UTG #6-48 screw to attach the ACE to the mount.
