These scopes are used by a great many shooters.
They are not a Nightforce or S&B, but they are way ahead of the competition in their price range.
Your current Leupold will have about 15 minutes more usable shooting time in the early morning/late evening than current production units.
With the comming glass upgrade (I'm testing now) there won't be any optical advantage to the more expensive scope.
I've been shooting these things since they were under Navy contract in the '80's and you had to buy them at Mil contract price (I paid $799.00 for my 1st unit) from Hoffman Enterprises.
I still use them and am currently testing the beta of a new unit with upgraded glass.
Both old and new SS scopes track perfectly. I beat the crap out of my stuff..intentionally because the factory wants a busted unit, and have yet to break one.
The SS scope is on a very short list of best buy for dollar spent items in the shooting industry.
Here's a link to some pics of what's in the works.
