FAB Defense Front and Rear Flip-Up Set

The FAB Defense RBS is a low-profile, dual-aperture rear sight designed for faster target acquisition and improved accuracy. It can be used as a primary or back-up sight, features tool-free windage adjustment, instant spring-loaded deployment, and a snag-free folded profile. Its ergonomic wing-shaped shroud helps center the sight picture, especially when paired with the FBS front sight.

The FAB Defense FBS is a matching low-profile front sight with tool-free elevation adjustment and the same durable, spring-loaded deployment. When used together, the RBS and FBS create a precise optical tunnel for faster, more accurate aiming.

Both sights are made from high-grade polymer and metal, fit all 1913 Picatinny rails, and are designed to be durable, lightweight, and easy to use.
