Probably the slickest .22 rifle I ever owned was a Remington model 341. Action was just plain perfect. Mine came with a simple yet excellent peep rear sight. No way to easily mount a scope but I did not want one on it.
The Ruger 10/22 deserves it’s popularity.
Another slick one was the Stevens Crackshot.
If money is not scarce, probably one of the CZ .22 bolt actions. Also if you can find one, A Winchester model 52 sporter.
Many, many really good .22s out there.
There is something most people don’t know, you can take the 39A rifle with a coin.
What does that mean?
