"Fun" seems to be a common term in these responses. I'll echo it. My 15-22 is an absolute blast to shoot. My 10 year old loves it and we enjoy finishing range trips with multiple mag dumps. Those same mag dumps with our ARs would cost me about $50. With the .22, it costs me about $4.
Accurate, accepts accessories that my ARs use and it's a familiar platform.
Now, I'm also love my early 1950's Remington 521t bolt action and single shot Savage with octagonal barrel. My dad doesn't want to touch a rifle without a wood stock.
So I see both sides and also see a fit for everything out there.
