Set: FAB Defense FRBS FDE Rear and Front Sight for Picatinny Rail
We offer a universal set of FAB Defense FRBS sighting devices, designed for quick and accurate aiming on modern M4/AR-15/M16 platforms. The set consists of two main elements that complement each other and form a reliable sighting tunnel for quick target acquisition.
- FAB RBS folding low-profile rear aperture sight
- FAB FBS folding low-profile front sight
Both elements are designed for installation on a Picatinny 1913 MIL-STD (Weaver/Picatinny) mount, making the set compatible with a wide range of weapons. Thanks to their correct geometry, they increase aiming speed and improve accuracy, creating a clear optical tunnel between the rear and front sights.
Key Advantages and Features
- Dual aperture rear sight — two distinct apertures: 3 mm for quick aiming in low light conditions and 1.5 mm for maximum precision.
- Ergonomic front sight hood in the form of two converging wings facilitates target centering in combination with any rear sight.
- Instant aperture selection is made by the shooter effortlessly.
- The set can serve as both a primary and backup sight.
- When folded, the elements of the set have a low profile: they do not interfere with equipment, do not snag, and do not rattle.
- A reliable mechanism with a spring-loaded detent ensures strong fixation — the sight will not accidentally fold or deform.
- Front sight height adjustment is tool-free, intuitive, and fast.
- The construction is made of impact-resistant fiberglass-reinforced plastic and metal, guaranteeing durability and resilience in field conditions.
