I have a half dozen Swarovski 3-9x36s on various rifles for mountain hunting. Mainly sheep type rifles. I think they are a great scope especially for the money. I have lots of miles on horseback up north with a swaro 3-9 on a rifle in the saddle scabbard and lots more on foot backpacking. I've never had a problem. I've even bought some used ones and sent them off to Swarovski. They put in new lenses, seals, and tune them up for little cost if any. Light, functional scope IMHO. Good resale also.
