Um..
Well, actually don't have a clue..
All I can tell you is the most accurate FOR ME 22 rifle I've ever owned. I'm an old fart (68) so 50 yards is about as far as I can actually see well enough to "hope" for a good group..
With that range, or less, in mind I have found, surprisingly actually, that my Marlin 39 Century Limited (1970) lever action (blinged up Mountie I believe) with the all steel model 70 Redfield Peep Sight is about as good as it gets.
Several months ago I bought the CL from the original owner who had replaced the factory iron sights with the Redfield and taller front sights early on, and it is a joy to shoot.
I believe I paid $465 off GB for the rifle plus shipping ($30), and ffl transfer fee locally ($25). So I guess I have $520 or so in it, but folks tell me the old Redfield model 70 is worth a hundred bucks or so..
Everyone has a particular 22 rifle they enjoy and recommend, and I have another CL, also a Marlin 39A, a couple of Browning SA22's and a sweet Winchester 63, which are all pretty accurate, but it seems when I just want to make holes in paper in the back yard I pull out the CL...
Best Wishes, and hope you'll find just what you're looking for.
