The UNITY Tactical FAST Micro-SB DUTY/COMP M5S BK is designed specifically for Aimpoint CompM5s, CompM5b, and Duty RDS mini red dot sights, delivering a robust mounting solution with a built-in, fully adjustable front and rear back-up iron sight that remains visible under UNITYs FTC magnifier mounts. This micro sight height is purposefully set with a non-standard BUIS height of 0.95" to accommodate a lower profile optical setup, while the front post is factory installed to ensure reliable zero and fast transition between optics and irons. The result places the taller micro sights at a 2.26" height to optical centerline, optimizing ergonomic cheek weld and aiming posture without sacrificing compatibility with magnified systems. Built from 7075 T6 aluminum and finished with a durable anodized coating, the FAST Micro-SB ships with a 2 cross bolt rail clamp for secure, repeatable mounting, and remains compatible with the FAST QD Lever for faster tool-free adjustments when needed. The mount is purpose-built to integrate seamlessly with Aimpoints Comp M5B and Duty RDS platforms, offering a proven, mission-ready solution that supports precise alignment, rapid target acquisition, and dependable backup sight functionality in demanding field conditions.
