the best is a lot of $$$$ how much you what to spend?
If you are not shooting past 100yd, a good one would work.
Burris is good for the price,the upper end Bushnell,Nikon,Vortex and of choose Leupold.
The Midas is also a good scope....and the new upper end Hawke.....there ar plenty more.
It would help if you were more specfic,like price range ,use,what it will be put on .
