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.
Notes: 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.
