UNITY FAST MICRO-SB DUTY/COMPM5S FDE

The Unity Tactical FAST Micro-SB is a fixed mount engineered specifically for Aimpoint CompM5s, CompM5b, and Duty RDS mini red dot sights. It bridges a critical gap in duty and patrol setups: these compact optics sit lower than full-size frames, which is why Unity built integrated backup iron sights right into this mount. The BUIS are factory-installed and fully adjustable, giving you a reliable fallback without requiring a separate front post—and because they're designed at a non-standard 0.95" height, they work in harmony with the optic's positioning rather than fighting it.

This is a no-compromise duty mount. The 2.26" sight radius puts your optical centerline at a height that pairs seamlessly with standard magnifier mounts, meaning you can stack magnification on top without awkward sight geometry. Built from 7075 T6 aluminum with a hard-anodized finish in flat dark earth, it's tough enough for patrol and service rifle work. The mount ships with a robust 2 cross-bolt rail clamp that locks solid to any Picatinny rail, and if you prefer quick-detach capability, it accepts the FAST QD Lever (sold separately) for rapid transition or gear rotation.

Whether you're outfitting a duty rifle, a home defense platform, or a precision patrol gun, the FAST Micro-SB removes the guesswork from miniaturized red dot mounting. You get a purpose-built solution that keeps your zero intact and your backup sights visible, even under magnification.

Frequently Asked Questions

Will this mount work with my Aimpoint CompM5s or Duty RDS?

Yes—the FAST Micro-SB is purpose-built for Aimpoint CompM5s, CompM5b, and Duty RDS sights. The mount is engineered to house these compact optics and position them at the correct sight height for duty and patrol rifles.

Can I use a standard AR front post with the built-in backup sights?

No. The integrated backup iron sights are fixed at a non-standard 0.95" height and come factory-installed. They are not compatible with traditional front posts (which typically run 1.41" tall). The BUIS are the backup solution—no additional front sight is needed.

Will the backup sights be visible if I add a magnifier?

Yes. The mount's backup iron sights remain visible even when stacked under Unity FTC magnifier mounts, thanks to the 2.26" optical centerline height.

Does it come with a QD lever, or do I need to buy one separately?

The mount ships with a 2 cross-bolt rail clamp for standard Picatinny mounting. The FAST QD Lever is sold separately if you want quick-detach capability.
