I also really liked the Elite 3200 10x40 mil-dot......till I learned that it had no parallax adjustment. It's going to be set at 100 yards. If you're going to be shooting longer ranges, don't get a scope without an adjustable objective or side focus !!
And sure, I guess you can get by with the above recommnded 7x or 9x scopes, but at 600 yards, you're very likely going to wish you'd gotten something with a little more power, especially when the 600 yard efforts tempt you to make even further shots.( and remember, scopes bought for one rifle often someday end up on another).
Also, I've read numerous Bushnell banner owners getting years of good service out of them, but the one I had ( came stock on a Beeman R9 .20 pellet rifle) screwed up quickly. Fortunately, once sent in to Bushnell, they allowed me to upgrade VERY reasonably to a 5-15 3200 Elite tactical, which I'm very happy with.
As I and others have already said, stay away from the Barska junk. If you have no problem spending 200-300 bucks, why shortchange yourself and get something that 95% report as disappointing crapola ? Good luck, keep us posted....
P.S. Here's another option,especially if you're counting pennies....

This is the 5-15x Bushnell Legend, which I believe is their best scope before getting to the Elite series. It also has their great life-time guarantee,has parallax adjusment,mil-dot reticle, AND has fully multi-coated lenses, features I don't think ANYONE can touch for $209 !!
