FAB Defense Flip-Up Front and Rear Sight
The FAB Defense polymer sight set is a lightweight, reliable backup sighting system for your AR-15. If your red dot sight runs out of power or breaks in the field, these sights spring into action and keep you in the fight. Both front and rear sights feature tool-free adjustment, and attach directly to any 1913 picatinny rail.
These sights are constructed from lightweight high-grade polymer, and can be used as a primary or secondary sighting system on your rifle.
Form, Function, and Precision
Both front and rear sights feature an “angel wing” shroud, which protects the front sight post and rear apertures. This matching shape allows you to align the sights faster, and get on target with a natural optical tunnel. They also feature a spring-locked deployment mechanism that won’t slip, break or deform.
Features
- Can be used as a primary or back-up sight
- Ergonomic angel wing-shaped shrouds helps center the sight image, creating an optical tunnel that ensures more accurate aiming and faster target acquisition

- Dual rear sight apertures are 3mm for longer eye relief mounting, low light, and faster target acquisition; and 1.5mm for shorter eye relief mounting and greater accuracy
- Instant spring-locked deployment mechanism will not slip, break or deform
- No tools needed for easy, rapid elevation and windage adjustments, with positive detent locking
- Made of extremely durable high-grade polymer and metal
