The Troy Industries Di-Optic Aperture (DOA) is the future of flip-up iron sights; with an advanced design, superior sighting speed, and battle-ready toughness. These sights provide lightning fast target acquisition and are manufactured to exceed military specs. The optically engineered apertures center your eyes instantly and effortlessly providing a clearer target picture than with round apertures.
The Troy DOA sights feature two settings, one for up to 300 meters and a second for up to 500 meters. This versatility makes the DOA ideal for military, law enforcement and home defense applications.
Troy Industries makes three sights; standard, medium and micro.
The measurement to the center of the standard aperture is 1.36”.
The measurement to the center of the medium aperture is 1.276”.
The measurement to the center of the micro aperture is 1.16”.
The standard & medium sights are meant for Mil-spec top rails and the Micros are meant for the enhanced weapons such as the IAR, Robinson Armament XCR, Heckler & Koch 416 & 417, and other weapons with raised top rails.
