Advanced, Low-profile & Durable Auxiliary Rear Back-Up Sight

The FAB Defense RBS Rear Back-Up Sight is an advanced, low-profile, and durable, auxiliary rear sight that can be readily mounted on any 1913 Picatinny rail, making it ideal for use on M4/AR-15/M16, TAVOR platforms, and on the FAB Defense(R) KPOS.

It is made from extremely durable and lightweight high-grade polymer that can be used as a primary or back-up sight and works accurately in conjunction with any front back-up sight or other optics.

Ergonomic Angel-Wing-Shaped Front Shroud

The FAB Defense RBS Rear Back-Up Sight has an ergonomic angel-wing-shaped front shroud that helps center the image with any rear sight. It can be used with any front sight but has been designed to provide an extreme optical advantage when paired with the FAB Defense® FBS Front Back-up Sight.

The RBS creates a precise optical tunnel that ensures more accurate aiming and faster target acquisition. It also features an instant spring-locked deployment mechanism so it will not slip, break or deform and allows easy and rapid elevation adjustments with positive detent locking with no tools required.
