I would ithink that there are a lot of those sights out there on the used market. It's a pretty basic sight, but if you aren't making a lot of adjustments after getting it sighted, it does OK. If your intent is to compete in long range stuff with it, don't bother. It isn't much for repeatability. Pedersoli also offers a couple of other sights that are listed in Cabela's shooting catalog that offer much more precision, but the price goes up. I changed out the eye cup for an adjustable one, and it worked OK on a rifle I shot for awhile that had the basic vernier sight. I had a BC with the mid-range sight installed that was pretty solid. But the sight you referenced is serviceable, if you are not looking to make numerous adjustments all the time.
