I'll throw my $.02 in here
I don't think you are looking at a particularly rare gun and they were cataloged for several years. But they are discontinued so that means a little something. The price stands out to me when you compare what some asking prices are on places like Gunbroker and what the new models cost. If that rifle is taken care of you'll be able to enjoy it , shoot it , and never lose money on it.
It has been 15 years since I passed on a new one at a local shop and the price then was $650 so I'd say you're looking at a pretty decent deal.
