The Troy Di-Optic Aperture Folding Rear Sight is engineered for rapid sight alignment and consistent accuracy under demanding conditions.

Built to exceed military specifications, the DOA rear sight is a proven solution for duty, defensive, and hard-use rifle setups.

Note: Designed for same-plane rail systems only. Not compatible with railed gas blocks that are higher or lower than the receiver. Compatible with Troy gas block front sights.
