Looking for rock solid stability and dead-on accuracy in a fixed sight? Advanced design, superior sighting and BattleReady™ toughness define Troy Industries Di-Optic Aperture (DOA®) fixed sights. Troy Industries Di-Optic Aperture (DOA) fixed sights gets the job done with an advanced design, superior sighting ability and BattleReady toughness. This permanent, rail-mounted alternative to a standard A2 sight allows limitless mounting options on all-length rails with a serrated ramp to eliminate glare.

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 sights feature two settings, one for up to 300 meters and a second for up to 550 meters. This versatility makes the DOA ideal for military, law enforcement and home defense applications. These advanced sights have been extensively field-tested and like all Troy Industries products are BattleReady.

The front post is centered between two Tritium points of reference to allow proper alignment.
