Gee Whiz... the last numbers on my rifle are 03. I am pretty sure that indicates the year it is made. It was the very first inline rifle that was not mailed back to the store. And I purchased the rifle new from Natchez.Com I think it was. Maybe Bass Pro Shop. So I have the newest rifle.. Also the trigger on mine is exceptional. And I know I gave $89.00 for it. Only the best scope for mine.. a $19.00 Simmons 4x32 Pro Sport Shotgun scope. But that this is sure a good shooter.
