Set: FAB Defense FRBS Black Rear and Front Sight for Picatinny Rail
Introducing the versatile FAB Defense FRBS sight set in black, designed for quick and precise aiming on 1913 MIL-STD Picatinny rails (M4/AR-15/M16). This kit combines the folding low-profile FAB RBS rear sight and the folding low-profile FAB FBS front sight, creating an optical tunnel that significantly increases aiming speed and shooting accuracy.
Kit Contents
- Folding low-profile FAB RBS rear sight
- Folding low-profile FAB FBS front sight

Features and Benefits
- Dual aperture rear sight: features two apertures — one with a 3mm diameter for quick aiming and effective shooting in low-light conditions, the other with a 1.5mm diameter for more precise aiming.
- Ergonomic front sight housing: the two-wing shape converging at the top helps easily center the target in combination with any rear sight.
- Instant aperture selection by the shooter without additional tools.
- The set can be used as a primary or backup sight.
- When folded, the rear and front sights have a low profile: inconspicuous, do not snag on gear, and do not rattle.
- Instant installation mechanism with a spring-loaded detent — the robust design will not break or deform spontaneously.
- Tool-free front sight height adjustment ensures quick adaptation to the shooter's needs.
- Materials: impact-resistant fiberglass-reinforced plastic and metal — a reliable combination of durability and lightness.
- Compatibility with 1913 standard Picatinny (Weaver/Picatinny) rails — suitable for AR-15/M4/M16 and related platforms.

The use of impact-resistant reinforced plastic along with metal elements provides a balance between weight and durability.
