OP said “best”, no mention of price range or intended use.
I’ve had a Rem 40X Sporter with clip, Kimber of Oregon, Win 52 custom and a Cooper. The Cooper stayed, others went down the road. Cooper is the finest all around .22 LR I’ve ever handled and for a number of reasons. Mine wears a Kahles 2-7 rimfire scope, a perfect match for the rifle.
