I finally had decent enough weather that I could get out and shoot the new 2500X with the Sightron S3. I really liked the scope and really loved the gun. It is going to be a shooter I think. The scope is clear and bright, tracked well and adjusted precisely. I found the parallax a little finicky but nothing that wasn't dealt with in 30 seconds of fiddling. I wouldn't hesitate to buy another one.Just to update everyone, I was looking for opinions for an ARA UL gun that is being built. I just bought a new ARA factory gun and, I bought the S3 10-50 x 60 with the target dot to try on it. I almost bought the NF benchrest for it but, I wanted the side focus. I still need a scope for my ARA UL gun that is coming and, depending on my opinion of the S3, I will make a decision on which scope to put on the UL gun. It could be another S3, the SV or the NF Comp. I will let you all know what I think of the S3 and where I'm going from there.
