In response to the 5-20 re-release question, it appears they are doing it.
Of course, do not wait to scope your rifles waiting for it. But I believe they are moving forward with this, and then the 3-9 perhaps this decade
I emailed SWFA the other day (before I knew about the S2H scope) and asked if a replacement for the 5-20 was in the works and I got a response...
"A replacement for our discontinued SWFA SS HD 5-20X50 is in the works. I will offer a different magnification but that is all I can say about it now. We are hoping to release the new scope later this year."
Just passing that tidbit of information along. Seems like big news to me.
