I bought one (for my son.....yeah, right!) about two years ago, and we have put thousands of rounds thru it without any major problems. I have learned to keep the chamber clean, or extraction can get iffy, but as long as I do what I'm supposed to, the gun does too. On days when I just want to hike a little and shoot a bit, there is no better gun. It's light, accurate, and the lever has to be worked to be believed. Mine is so slick it makes my Marlins feel clunky, and I love my Marlins! Buttery smooth action. Mine got gummy after about 2000 rounds, so I tore it down and cleaned it up in about ten minutes. Takedown and re-assembly are easy, even for a beginner.
My one complaint involved the cheesy, extra-wide front sight blade. Five minutes with a file, and I had re-contoured it into a point, now precision shooting is a lot easier.
Considering the cost is about half what a Marlin 22 is, I'm very happy with it. The receiver is aluminum, but hey, it's only a 22! Who needs more?
