It's mounted on a .308 and I've range 8" steel out to 600 with it. Clicks are easy to feel and it tracks very well.
It is NOT a night force, but it's a very durable scope that will hold zero and has decent clarity. I did have trouble with the 500 yard plate because it was rusted about the same color as the berm. Being only a 10X scope made it hard to distinguish.
Also, it's doesn't do well with flip up covers since its got the focus on the eyepiece instead of being side mounted.
Overall, I would buy it again. When I upgrade I will be going with a SWFA 5-20 HD. The 10X will stay will me and go an another rifle.
SWFA also has great customer service whether in store or on the phone. Great people to deal with.
