While most folks wouldnt do it, I decided to put a Zeiss Conquest 6.5x20x50 on one of my 17's. It works very well for me with the side focus and target knobs. Adjustments can be quickly made for different distances and it didnt take me long to learn where they need to be for the longer ranges. I do know that the little 17 starts dropping like a rock at 150 yards. I have always been a beleiver in you cant hit what you cant see and with the higher magnification and quality that the Zeiss delivers it gives you an edge.This scope is excellent but does run more than most.
