I picked a demo up for a pretty good price. I put it on a new X-Bolt and really like how it shoulders with the great eye relief. Planning on getting some rounds down range soon...too much snow yet around my area. I had a few questions and contacted Steiner and they were great about getting back to me answering all my questions...even sent me a set of covers for free even though they were not supposed to come with my 50mm model. I have read that they had some issues with tracking early on but those have since been corrected and mostly great reviews since then.
