Unity Tactical FAST Mount for Holosun AEMS


Flat Dark Earth (FDE)

Product Description

The FAST™ AEMS positions Holosun™ AEMS™ optics at a 2.26″ optical centerline from the rail. It comes standard with a two cross bolt rail clamp, but is compatible with the FAST™QD (Quick Detach) Lever. It can be paired with any FAST™ FTC (Flip-to-Center) magnifier mount.

FAST™ is a series of optic mounting solutions that provides end users with a quicker sight picture than standard height mounts. FAST™ mounts create a 2.26” optical centerline from the rail, which allows for more rapid visual processing of the battlefield by ensuring an ergonomically correct heads-up posture. Further, they provide faster and easier dot/reticle acquisition while wearing night vision goggles, protective masks, plate carriers and other gear.

*NOTE: “FDE” is used throughout our catalog to reference a spectrum of colors that include tan, brown, bronze, earth, and everything in between. Due to the chemical process that takes place during Type III Hardcoat, the final finish can vary from part to part (even parts done in the same batch). Therefore, your “FDE” product may vary from other parts from UNITY and other companies, and may vary from the photos shown online.
