Anyone tried one? How do you like it?

I have a few 4200's on hard recoiling rifles (light weight 338's and 340 weatherby's). They have held up through 100's of rounds.
They are tough! and very good optcally from my experience but I cannot speak for this new offering 1.25 X 4.
I would try one out. They are typically not that expensive. I may buy one and put it on a 458 Lott if it has enough eye relief. That is a good test!
