Used to see them quite often but verrry seldom now, and as mentioned, they're pricey when found. My brother mentioned them a short tim ago saying the parts for them are getting more difficult to find as well. (kinda makes sense) With that, if you're one that has to have spare parts for your guns, think before buying one.
Sad but only way they'd sell enough to warrant production now is if they made it with a polymer stock and Picatinney rail. Yuck!
