This Rear BattleSight features Troy's unique Di-Optic Aperture, designed to provide lightning quick target acquisition when paired with a traditional M4 style front sight.

The optically engineered aperture centers your eyes instantly and effortlessly providing a clearer sight picture than that of round apertures.
