Rob Pincus used the Primary Arms SLx 3x MicroPrism optic on an AR for several months and shares his experience with it. He and other instructors used one on the 2022 PDN Training Tour.

The optic is three times magnified – it’s not a 3x magnifier; it’s built in. Rob was at first skeptical of this as he has spent a lot of time looking through fixed-magnification red-dot sights, specifically fixed 4x, and did not find them useful at close range. But having worked extensively with the Primary Arms SLx 3x MicroPrism, Rob can state that it does not slow him down in close quarters.

ROLES FOR THE 3X MICROPRISM

Rob feels it’s a good fit as part of defensive gear for home defense but if you want the magnification for work around/outside your home, around a vehicle, or for a patrol rifle in a rural environment, it’s impressive.

SPECS

Primary Arms MicroPrisms use an etched reticle. (Rob examined the Primary Arms SLx 1x MicroPrism in an earlier video.) This 3x has the ACSS Raptor in it. If the battery goes down, you still have the aiming point inside it. Backup iron sights are not needed.

The 3x MicroPrism has 13 brightness settings. Windage and elevation are tool adjustable. It’s a ¼ MOA click and you get 80 MOA of adjustment. It comes with eight different configurations for setting up the mount, so whether you have an AR, AK, or PDW, you’ll be set.

Eye relief: the 3x MicroPrism has an adjustable diopter. The eye relief is stated to be 2.7 inches but Rob’s experience is that it’s pretty forgiving. He demonstrates how much he can move his eye toward and away from the optic and not have any shadow. This is a plus when having to get on the rifle quickly and when in unorthodox shooting positions.
