Unity Tactical’s FAST risers are one of the most popular ways to mount an optic high above a rail. Those risers exist for many popular optics like Aimpoints, EOTechs, and various LPVOs. Well, add the Primary Arms MicroPrism family to that list now, too.

The Primary Arms MicroPrism line includes 1x, 3x, and 5x options. One of the notable features of that product line is its adaptability to various mounts. However, those mounts top out at 2.075 inches high. For some users that just is not quite high enough. Fans of night vision and people who wear gas masks all appreciate very tall mounts, and the Unity Tactical FAST mount is made for those uses.

As with the other members of this lineup, the MicroPrism mount uses standard Torx-head screws to clamp it onto the rail. But for those who need a little extra razzle-dazzle, Unity Tactical also sells an upgraded QD lever for $40, if that’s a feature you are looking for. This new FAST Mount is available from Unity Tactical and Primary Arms as of writing. Unity has both the FDE and black models available for $186. Primary Arms has both models in stock for $169 each.

From the manufacturer:

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 or can be retrofitted 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.
