Questions & Answers
Would a Larue Aimpoint T-1 Micro ring mount fit on this optic? Expert Answer

No, the Primary Arms SLx 5X Micro Prism does not utilize the Aimpoint T1 mounting footprint and would not be compatible with T1 pattern mounts. It uses the Mini Prism/Mini ACOG footprint.

Helpful Positive Review Awesome sauce by Birdman, September 9, 2023
If you are strictly target shooting this isn't the scope for you. But for an all around multi-purpose scope this one is great. It is small and LIGHT! About a third the size and weight of popular variable power scopes. The glass is clear, the reticle ...

Helpful Positive Review PA5x micro prism scope by Gregory, February 20, 2024
I just purchased this product so my time at the range is not enough for a thorough evaluation. It has a smaller eye box than my full size model but the same reticle and that in itself is optimal for speed and acquisition of the target. It feels solid...
