I was planning to buy an Elcan 1.5/6x scope for my 17. I was very certain that it was the optic I was going to get until the video above. After watching the video it raised concerns. So now I was wondering what is the general take on the Elcan and what other users have to say? I know some guys here have them and I know some of them use and abuse their pretty good. So this leaves me with questions like; is this an old issue or a defective model? Can this be fixed? I saw another video that demonstrated an impact shift when force was applied to the spring mechanism mentioned in the video if I remembered correctly. I know these optics see action with our nations best in adverse conditions, with that being said is there any reports of impact shifts when debris has worked it's way into that portion of the mechanism? Any feedback with links or report would be great.
