Frequently Asked Questions
Will this rear sight co-witness with my existing front sight?
Yes. The Ruger Rapid Deploy Rear Sight is designed to co-witness with standard A2-height gas block front sights commonly found on AR-platform rifles. If you are running a low-profile gas block without a front sight, you will need a compatible A2-height front sight tower or a flip-up front sight set to the same height for a proper sight picture.
Can I use this sight alongside a red dot or magnified optic?
Absolutely. The folding design is specifically engineered for use with optics — when not needed, the sight folds completely flat so it does not obstruct your scope or red dot. When your primary optic fails, a quick press of the button springs the rear sight upright for immediate use as a backup iron sight (BUIS).
Is this sight compatible with any Picatinny rail, or only Ruger rifles?
While Ruger designed this sight to integrate seamlessly with their SR-22 Rifle, AR-556, SR-556, and SR-762, it is compatible with any modern sporting rifle featuring a same-plane MIL-STD-1913 Picatinny rail. This makes it a versatile BUIS option for a wide range of AR-15 and AR-10 pattern rifles from any manufacturer.
