UNITY Tactical FAST MicroPrism Mount for Primary Arms Black

Available from stock with us. Pay attention to the respective delivery time indication.

The Unity Tactical FAST Micro Prism Mount raises the optical axis of sights with a Primary Arms Micro Prism compatible footprint to approximately 57-61mm (2.26"). This not only corresponds to current shooting concepts that emphasize a straight, relaxed head position for more dynamic shooting disciplines but also helps "tall guys" achieve a more comfortable shooting stance. For the hunter, the elevated optical axis is advantageous when using night vision goggles. The mount is also extended forward to sit on the housing of an AR15 while still providing valuable centimeters of forward space for optics, allowing magnification modules to be positioned further forward, which is of course also beneficial for our taller shooters and simplifies the use with night vision goggles.

Made from 7075-T6 aluminum and Type III hard anodized, the mount is lightweight yet very robust. The clamping jaws can be replaced with an optional QD lever. We recommend using this riser with sights from the Primary Arms Micro Prism family, including the 1x, 2x, 3x & 5x models.

What is "co-witness" anyway?
"Co-witness" refers to the ability for the optical axis of a red dot sight and a standard sighting system to be at the same height, allowing both to be used simultaneously. On the AR platform, this height is approximately 3.5cm (1.4"). Since this sight height is considered somewhat too low for dynamic disciplines and the field of view of the red dot sight is significantly restricted with a fixed or flipped-up sight, the currently most used standard is the "1/3 co-witness," which states that the standard sighting system is located approximately in the lower third of the field of view of the primarily used red dot sight. Depending on the manufacturer, there are slight variations, but this sight height is around 37-41mm (1.5"-1.63"). The Unity Tactical FAST Optical Riser is designed for this sight height.
