I've had two over the years. I loved them both. One spent many years on my Anschutz 1413 and the other lived on my 222 High Wall. These are great scopes... for their purpose. Also note that I was much happier with the scope on the Anschutz than the one on the 222. I never could prove it, but I always thought that the scope on the High Wall changed POI after the barrel got really warm. Remember: this scope has internal adjustments and the mounts are rigid. A Unertl target scope, on the other hand, is allowed to slide for-and-aft and is held into battery with a spring. I found that the Redfield was a bit brighter than the Unertl, but the Unertl is far more flexible in mounting, adjustment, and repeatability. In my case, my 1413 was dedicated to 50-yd small-bore match. Everything was tweaked to 50 yd, and the zero changed only when I changed lots of ammo. For this, it worked great.
My humble opinion: it is a fantastic scope... for small bore. BTW: finding mounts may be a problem. The rear mount... no problem at all. It goes on the receiver bridge. The front mount, however, goes on the barrel. The mounts on my Highwall were custom made from a set of Remington 700 "donor" rings. Plan on having the front ring made by a competent gunsmith. As for value, I sold a 24X, in excellent condition, on eBay. Got $485 for it. A place called ABO used to be the "official" US repair center for Redfield. I have never used their services, nor do I have any knowledge of the quality of their work.
