Did you know that Ruger makes a 10-22 Air Rifle? Yup, first I ever heard of one by Ruger, but I have an Ad in a Wholesaler catalog... $94US wholesale Price...
There is a conventional barrel-cocker pellet rifle under the Ruger brand too. Browning markets a "Buckmark" air pistol. All the gun manufacturers are marketing air guns. I have a Winchester pellet rifle. Most are Chinesemade, with the American company's name stamped on it.
