jimbo1096 - The full length laminated stocks were on a WalMart special stainless 10/22 RBI from over 10 years ago, IIRC. They still turn up used from time to time on GB, GA & AA. I believe there were also distributor special 10/22 runs with laminated Mannlicher stocks.
I found and bought one of the WallyWorld ones (1995 manf. date). Then I found and bought one of the new model 10/22 RBIs with a blue finish and a beech stock (1996 manf. date). This one and a stainless/beech version were last in the catalog in 2003. Then it was just a matter of switching stocks since I greatly preferred the look of a blued rifle in the black & white laminated stock. So you can call it "unique" or call it a "mutt".
