I was able to get a S&W 15-22 performance model about 6 months ago, expensive, but fun.
Hung a scope on it, shoots OK, getting better.
Like all 22 rimfires, it likes one or two ammos, and definately not cheap stuff.
S&W says no to a list of ammo brands, listed in the manual. CCI stingers no because of the longer case, and the performance chamber.
Mt grandkids love it as well. I had an extra Gieselle dynamic trigger, and that fixed a 6 # trigger.
lots of fun, but still love my lr-308.
