Description
Unity Tactical FAST Micro-SB Mount
The Unity Tactical FAST Micro-SB is specifically designed for the Aimpoint CompM5s, CompM5b and Duty RDS mini red dot sights and features a built-in, fully adjustable front and rear back-up iron sight. It puts these taller “micro” sights at a height of 2.26″ and is fully compatible with the entire line of FAST FTC magnifier mounts. It comes standard with a 2 cross bolt rail clamp, but is compatible with the FAST QD Lever (sold separately).

I got two of these mounts for an Aimpoint T2 and Holosun 403R (the cheap T2 clone). The Fast MICRO-SB is made for the Duty RDS/CompM5s with the taller optic body, but, I do not want to run the 2.26″ optic height because of the inadequate cheek weld (for me), and it is rough shooting prone, but also, I want built in BUIS to make myself feel better about not running a separate set of BUIS. I don’t want to run BUIS to cut down on clutter out front, and for more rearward magnifier positioning for eye relief.
This has been the perfect solution. With the T2’s shorter housing, it sits at 1.8″ height. Higher than common 1.57″ lower 1/3 height, but lower than the getting tallish 1.93″ height. (The 403R housing is a little taller that the T2, so I am guessing that one is closer to 1.85″ height).
The built in BUIS are very low on the MICRO-SB, though still totally useable in a pinch, but they are BUIS, and will likely never be used or needed.
I use a EOTECH G45 magnifier, and with the lower 1/3 spacer installed on the factory QD mount, it sits between 1.7″-1.74″ height, which works great with the 1.8″ T2.
I learned recently that EOTECH’s lower 1/3 height for their optics is actually between 1.7″-1.74″, not the more common 1.57″ height. This goes for all of their magnifiers and their holographic sights. You could also pair a 1.93” magnifier with the 1.8″ red dot (I tried and it worked fine), but it requires more elevation adjustment on the magnifier. Not sure how well it’d pair with a 1.57″ magnifier.
In the end, this was a great solution for my particular issues, and I am very happy with how it turned out.
Additionally, Kenzie’s Optics customer service is 10/10. They helped me out with some last second order changes to be sure the right items got to me in the time I needed it. They exceeded expectations in every way and deserve your business.
