They have all been Leupold VX-I's. Mine a 3x9x40 and his a 2x7x33. Can't remember what my other friends was. They aren't Leupolds expensive line however at $225-$250 they are still expensive enough that they should not fail. He says he didn't drop his.

I'm using Leupold rings and a base but I'm not sure what the other two were using.
