I bought this scope at the same time I bought my S&W 15-22. I didn't put a lot of thought into the scope. It is easy to mount on picatinny rails, easy to sight, seems to hold a zero. I like the choice of red or green, and four different reticles. The problem is the zero changes when you change reticles. The difference was 2-3" at 25 yards. Might as well have been a mile. If I remember to use the same reticle every time it seems to hold zero just fine.
Pros: Easy to mount, versatile
Cons: zero changes when reticle changes
