Unity Tactical FAST™ Micro-SB Mount w/ Built-In BUIS (Aimpoint CompM5s / M5b / Duty RDS)

Overview

The Unity Tactical FAST™ Micro-SB Mount is purpose-built for taller “micro” red dot sights like the Aimpoint® CompM5s, CompM5b, and Duty RDS. It delivers the FAST™ standard 2.26” optical centerline for a faster, heads-up sight picture, while also integrating a fully adjustable front and rear BUIS that remain visible under all UNITY FTC magnifier mounts.

Unlike the standard FAST™ Micro mount, the Micro-SB uses a non-standard BUIS height (0.95”) that is not compatible with traditional front sight posts—so the front post comes factory installed and is intended to be used as a complete system.
