I have shot just about all of them and to my.mind the best .22 rimfire semi aito rifle designs from the 20th century were -
Browning 22 Auto
Marlin/Glenfield m60
Ruger 10/22
All of them can be extremely accurate out of the box when matched with ammo theh like. All could benefit from a bit of trigger work.
And of those three,a Ruger 10/22 modified to suit ones needs /taste is hard to beat in terms of pure performance and versatility..
