Brandon Ransby's Review of Primary Arms SLx 3x21mm Micro Magnifier Red Dot Sight

Great backup to the Primary Arms Slx 1x. Took a minute to zero to my slx but once it married looks great and sharp. When paired with Unity FAST FTC mount you can’t go wrong.
Pros:
  • Clear
  • sharp picture
Cons:
  • Diopter adjustment
  • take a minute to zero
Best Used for:
  • 1x red dot sights
  • 1X prism
Would Recommend: Yes
