I've heard some negatives...not a real AR upper or lower[not compatible]..little too much of an airsoft look or feel and some whining about plastics. Some recommend getting a dedicated .22LR upper to mate w/AR lower.

I just picked up a CMMG conversion unit on sale, <$200 w/two 26 rd mags..hope to shoot it tomorrow.

Having spread all that rain most folks I've heard from that have the Smith seem to like it, YMMV.
