UNITY FAST MICRO-SB DUTY/COMP M5S BK

The Unity Tactical FAST Micro-SB is a dedicated mounting solution built specifically for the Aimpoint CompM5s, CompM5b, and Duty RDS compact red dot sights. If you're running one of these micro optics on a modern rifle or carbine and need a rock-solid mount with integrated back-up iron sights, this is the platform designed for your setup. Unity engineered the FAST Micro-SB to position your mini red dot at a practical sight height while keeping those integrated BUIS visible and functional even when you layer it under a magnifier—something you can't do with standard-height backup sights.

Built from 7075 T6 aluminum with a hard anodized finish, the mount is constructed to handle duty use and field conditions. The integrated back-up iron sights sit at a non-standard height of 0.95 inches, a design choice that lets them coexist with a factory-installed front post without the height conflicts you'd run into with traditional 1.41" front posts. The optical centerline sits at 2.26" above the rail, putting your CompM5s or Duty RDS in line with most magnified optic systems. Attachment is straightforward: a two-cross-bolt clamp secures to your Picatinny rail and locks down solid. If you prefer quick-detach convenience, the mount is compatible with Unity's FAST QD Lever (sold as a separate accessory).

This is the kind of purpose-built mount that separates tier-one equipment from improvised setups. Unity didn't design this for universal red dots or as a "will it work?" compromise—they engineered it to maximize the capabilities of these specific compact Aimpoint optics. Whether you're building a precision carbine, a duty rifle, or a system that needs magnification without sacrificing backup sighting, the FAST Micro-SB does one job with no apologies.

Frequently Asked Questions

Is the FAST Micro-SB compatible with my Aimpoint CompM5s?

Yes. The FAST Micro-SB is specifically designed for the CompM5s, CompM5b, and Aimpoint Duty RDS micro red dots. It will not fit other optic designs.

Can I use this mount with a magnifier?

Yes. The integrated back-up iron sights remain visible when the mount is used under Unity's FTC magnifier mounts, thanks to the non-standard 0.95" BUIS height. The 2.26" optical centerline is compatible with magnified optic systems.

What's included with the mount?

The FAST Micro-SB ships with a two-cross-bolt Picatinny rail clamp and a factory-installed front post. The back-up iron sights are built in and fully adjustable. If you want quick-detach capability, Unity's FAST QD Lever is sold separately.

Why is the back-up sight height listed as 0.95 inches?

Unity designed the BUIS at this non-standard height specifically so it can coexist with a traditional front post on the same mount without height conflicts. Standard-height front posts (typically 1.41" tall) would interfere with conventional backup sights at normal heights, so this design solves that problem.
