Derek's Review of Primary Arms SLx MD-25 Rotary Knob 25mm Microdot Red Dot Sight

This is an OK budget optic. It would have been better if it came with lens caps. My big issue with it is that the rotary dial to turn it on and adjust the brightness is VERY hard to turn. I reached out to Primary Arms and was advised that they are very stiff and I should use a rubber glove and sit in front of the tv to break it it. Yeah.... no.
It is a good size, the red dot is crisp and the glass is good. But I've already left a few layers of skin on the darn dial so I can't recomend.
Pros:
  • good size
  • good glass
Cons:
  • Rotary Knob HARD to turn
Would Recommend: No
