Check yer PM's I really like the one I bought new. Runs like a sewing machine, using Winchester M 22 round nose ammo, clean burning. If you come from an AR type background the controls might be a bit counter intuitive (so I have heard), never owned this type of rifle before so the 522, I know nothing different and feels very nice to me, I was told by the LGS owner that the S&W is a very good trainer for the AR15 platform. As you may have learned the 522 uses a magazine that is a M15 clone set up for .22lr and can be had for $10 ea!!!! I bought 4 right away so now have 5 25 round mags
