Optimize your firearm’s optic configuration with the Unity Tactical FAST Offset Optic Base FDE. This precision-engineered accessory delivers a modular platform for mounting secondary micro red dot sights at an optimal angle, enabling faster target transitions without compromising your primary optic’s field of view.
Key Features
- 35° Offset Angle – Positions micro red dots for rapid, intuitive access during dynamic shooting scenarios
- Modular Design – Bolts directly to compatible FAST mounts and accepts FAST Optic Adapter Plates for customizable footprints
- Ambidextrous Compatibility – Supports both forward and rearward mounting positions for flexible setup

Benefits for Tactical Shooters
Traditional co-witness setups can slow transitions or obstruct primary optics. This offset base solves that by providing an angled secondary sight option that keeps your head position natural and your primary LPVO or red dot unobstructed. The result is quicker target acquisition and improved situational awareness in competitive or defensive applications.
