Ruger 90415 Rapid Deploy Rear Sight - Folding Black Polymer - Fits Ruger SR-22/SR-556/SR-762

The Ruger Rapid Deploy Rear Sight is a lightweight, black polymer folding back-up iron sight custom-designed for the Ruger SR-22, SR-556, SR-762, and AR-556 rifles. It also mounts to any modern sporting rifle equipped with a same-plane Picatinny rail, making it a versatile backup aiming solution across the Ruger SR family and the broader AR-platform.

Part of Ruger's Rapid Deploy family, this rear sight is spring-loaded and pops up with the push of a button, then folds flat against the rail when not in use to keep the optic channel clear. Constructed from durable polymer in a non-reflective black finish, the unit keeps carry weight to a minimum while standing up to hard field use. It is windage-adjustable for precise zero and is engineered to co-witness with most A2-height gas block / front sights, giving shooters a reliable iron backup without sacrificing rail real estate for a primary optic.
