The XS Sight Systems CSAT rear sight is a Mil-Spec sight for AR-15 and M16 A2-style rears, designed for easy use and instinctive target acquisition.
Its same-plane aperture switches between precision and battle apertures without changing zero. The precision aperture is set to a 100 yard zero; the notch gives a 7 yard zero to remove the 2.5" offset in CQB situations. The aperture face has serrations to reduce glare.
