Description

The FAB Defense FX-FRBSOSB offset flip-up sight set delivers precision backup sighting for AR-15 platforms with mounted optics. These 45-degree offset iron sights allow rapid transition from primary optics to mechanical sights without removing hands from firing position.

What Makes This Different

Unlike traditional co-witness sights that share the same sight plane as optics, the FX-FRBSOSB mounts at a 45-degree offset angle. This configuration eliminates sight picture obstruction from scopes or red dots while maintaining instant accessibility. The spring-loaded flip mechanism deploys sights with positive detent positions, ensuring consistent zero retention across multiple deployments.

Key Features

45-degree offset mounting eliminates optic interference
Spring-loaded flip-up mechanism with positive detent locking
Mil-spec Picatinny rail compatibility for standard AR-15 platforms
Aircraft-grade aluminum construction with Type III hard anodizing
Low-profile design maintains weapon maneuverability
Windage and elevation adjustments on rear sight
Ambidextrous operation for left and right-handed shooters

The offset configuration proves particularly valuable in competitive shooting and tactical applications where optic failure requires immediate backup sighting. Simply cant the rifle 45 degrees to acquire the iron sight picture without optic removal or adjustment. The robust aluminum construction withstands repeated deployment cycles while maintaining zero consistency. Weather-sealed mechanisms resist moisture and debris infiltration during field use.
