I have the 611A varient, bought new, and can say there's not much difference in the hands of a shooter, between it & the earlier 611.
Once I got a peek at fit/finish of the issue BRNO/CZ rings the dealer had @ $65 extra cost - I opted to order a set of Burris/CZ rings from
www.swfa.com @ $30 with 2x better fit/finish.
Regular rimfire rings, or CF Weaver-type rings, won't fit the integral BRNO/CZ receiver dovetails.
Mine is nicely accurate with the 3 kinds/brands/types of Mag ammo I have on hand.
The only thing I find odd is the issue front sight arrangement - which I don't use anyway, since I put a Leupold Compact scope on the rifle.
I paid $500, about 8 years ago - and would gladly pay $700 for another NIB one today, if I didn't already have this one.
At THAT time, the earlier 611's were trading for about $150 more, because junkies deemed them "better" than a 611A - B.S.
