I bought this mount for my Trijicon Accupoint 3-9x40 and mounted them on my ar-15. After getting zero, I was shooting just under 2" at 100 yards with 5 shots. I then removed and re-attached to see how much, if any, deviation there would be. There was none. When you snap this mount into place you can feel how solid it is. I challenged myself by trying to hit a 3/4" splatter target and clipped the edge of it with 1 of 3 shots. This was my first experience shooting a scoped ar and I absolutely adore the combination. It is everything that I hoped for and more. Worth every penny.
Pros: Return to zero, Tight tolerances
Cons: None
