Well.. first I would say that you could spend the same amount of money and get a better rifle, but that is not what you asked.
I owned two of them, errr I had one and my wife had one. We shot them extensively for a number of years, and did like them. That being said, the biggest issue for any automatic feeding firearm, is magazines. Back when we had them, you could not get a Ruger magazine, so aftermarket it was. The best was PMI, which went under during the ban. We had a bunch of them, and they held up flawlessly for thousands of rounds. We also had trigger jobs done on ours from Connecticut Precision Chambering, and that helped a lot. Accuracy can be an issue, hence all the stuff out there to make them more accurate. I feel that ours were good enough, and decent. I would have no problem shooting them decently out to 200 with the irons, but I also accepted a 3MOA group at that distance as well. A scope would improve that some over using the irons.
One other problem is that it is difficult to get parts, or at least it was then. I was never able to obtain spares for ours.
