I received this 10X SSM in '99 and it has thousands of round shot and I prefer it to my Leupold 3-10 M3 LR. I remove it for transport and cleaning and it always shoots to the same point the next time I mount it. I don't know if anything has changed in how they are made now but I did hear SWFA changed manufactures at some point in the last ten years.
