The ECO from NcStar has a great combination of features. The optic is a 4x magnification blue iluminated urban tactical reticle as well as a forward mounted green laser and red/white NAV light. There is a backup rear peep sight and fiber optic front sight with three different mounting positions (Top, left 45°, and right 45°). The top of the ECO scope has an integrated NcSTAR® Micro Dot reflex dot sight base for mounting a secondary reflex optic to the top of the scope. There is also a 1.75" long Picatinny rail for mounting optics or accessories to the top of the scope.
