I also agree with the above 3 posts. If it were me, for that price, I'd throw in a little more and get the real AR. If I had to have one in 22, I'd go with the M&P, or one of the others, they're very nice, too, for like $200 less.
$600 and .22lr should never bein the same category.
What about some of those nice bolt action varmint guns? I am considering a CZ 453 Varmint in 17 HMR, about that price.......
