Troy Industries’ Dioptic Aperture (DOA) Folding Rear BattleSight combines advanced engineering with battle-ready durability. These sights deliver rapid target acquisition and are built to exceed military specifications. Machined from hardened aircraft aluminum and finished in Mil-Spec hardcoat anodizing, they install easily and deploy quickly. The sights are positioned at exact factory height.
The optically-engineered apertures are designed to center your eyes instantly, delivering a clearer target picture compared to round apertures. Two settings accommodate shooting distances up to 200 meters and up to 600 meters, making these sights adaptable across multiple use cases. The DOA is suited for military, law enforcement, and home defense applications. This sight is designed to work on same plane rail systems only and will not work with a railed gas block that is higher or lower than the receiver, but will work with Troy Gas block Front sights.
