I bought one of these a couple of years ago, one of the biggest pieces of dog doo I've ever owned. Sloppy, too heavy/unbalanced for a 22, poorly made, magazine danced around in the magwell like a midget screwing an amazon.
I believe I've made my opinion known. Spend the extra few bucks and buy a 15/22, or better yet a Ruger 10/22.
Palmetto State Armory has the Mossberg 715t new for $170. With that said I have heard a bunch of bad reviews about them.
I just picked up the M&P15-22 from PSA for $300. Good quality and fun shooter. If I were you I would spend the extra money and get an M&P15-22 or a Ruger 10/22.
