Unity Tactical FAST MicroPrism Mount


Flat Dark Earth (FDE)

Product Description

The FAST™ MicroPrism positions Primary Arms® MicroPrism™ optics at a 2.26″ optical centerline from the rail. It is also compatible with other optics of industry standard mini-prism footprint (heights may vary depending on the optic).

It comes standard with a two cross bolt rail clamp, but is compatible with the FAST™QD (Quick Detach) Lever.

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.
