I was looking for old style VX2 2-7X for the long tube. Couldn't find one at decent price so slapped on an old M8 4X.
Even then, I had to use one offset ring to slide it back enough (that ring at the rear position).
It was just a tiny bit into the offset, and it worked. But I moved it back a little bit more and will rezero.
Wearing a layers I had to crawl it a bit much last yr.
Mine is also an RSI.
