From the manufacturer

FAB Defense Top Mounted Deployable Front and Rear Sight for Right Hand Black fx-frbsosb. Made to withstand the toughest of them these sights will show you a sight that's built to endure and win every time. This is all possible because of the well thought out design of the Sight. Finely machined from a block of top-quality steel the Sight features dual reticles with a notch on the inner part of the ring allowing for proper front to rear sight alignment. The notch is made from a special hardened steel that ensures it will not break when impacted by the most extreme of recoil. With the raised rear ring the sight picture is greatly enhanced increasing the shooters visual FOV. This also prevents the sight from being impeded by an overly tight front sight base. With the included pin both front and rear flip-up sights are spring-loaded which allows the sight to flip up instantly as needed during use. Installation is made easy with the included pin removal tool. Sights install in just seconds using the included pin removal tool.
