For a 10/22, that's kind of a waste of money on that scope. I have a full-on custom 10/22 with a Valquartsen barrel, and all Valquartsen internals, etc... And it's still barely accurate enough at 200 for me to justify the Vortex Viper HS-T 6-24x50 that's on it... My point being, a 10/22 is never going to be accurate enough to justify an optic like that. I hate to be the bearer or bad news, but it just is what it is.
If you were running a custom Voodoo or Christensen Ranger, or something known for it's precision, then maybe you could justify it. But IMO, for any .22LR gun, that's just overkill.
A lot of folks have been buying the Arken EP5 for NRL and other comps, and have been enjoying them. They also have Japanese ED glass, excellent turrets, a 34mm tube, a solid zero-stop, and TONS of elevation travel adjustment.
