I'm thinking of getting an sr22 as my first rifle. I'm wondering which optics to put on. Was thinking of an ncstar 3-9x40, or possibly the BSA 3-9x40 scope. Is there any issues w/ the ncstar w/ parallax? would the bsa be better cause it's made for .22? Last question...would you put on burris high mount rings or use a cheaper brand? I'll likely be shooting at a range which only goes to 25 yards...until i can find somewhere better close to me, or some nice gravel pits in southern ontario
