I have been using the Leupold 171715 on a few guns for years now with no problems. Given all the stories I am quite suspect of them though. I once had a (non Leupold) scope ruin a hunt. No matter what the warranty is, you can't get your hunt back.
The 171715 is the VX5HD 3-15 with wind-plex. It suits the way we hunt. Dial for elevation, hold for wind. Relatively lightweight and wonderful glass for the price point. We won't be shooting an animal past about 800 in perfect conditions.
Have one on a Tikka T3 in 7 RM. It is our most used hunting gun. Been dropped/fell over twice on hunts, has resulting ding and scratches. In both cases an elk was taken shortly after. First was 330 yds no dialing required, and second was 660 yds dialing required. Both shot right where they should have. In the second case we had time to check zero after the gun was dropped - it was fine.
I still wonder about them though. The Tikka 7RM has a lot of hunting miles and a lot of range time practicing. I wonder if Leup just puts out a stinker from time to time or the design is just marginal. The stories that guys have are numerous and real.
If I were you, given what Formilidosus has done testing over at Rokslide, I'd go with a Trijicon or NF. Trijicon is what is going on my incoming Seekins PH2.
