i bought a redfield revelution 3x9 directly from leupold and had them set the parralex at 50 yds. i believe they make a 2x7
also.
I did the same thing with the 2-7x33 Redfield. I think Leupold charged me $15 to adjust the parallax. It's a nice set-up for a rimfire.
I also have the 4 power fixed Weaver rimfire on another 22. If you are on a tight budget, the Weaver rimfire is hard to beat.
Assuming you got a good deal on the 2x7 in the classifieds you have a win. I hope you like it.
