The model is catalog number K10/22-RP. To get this info, I had to take a serial number from a previous customer's rifle and submit it to Ruger. That specific rifle was manufactured in 1997, and this model was not a distributor's special, but a regular item available around that timeframe. It is no longer listed on their website, meaning it's no longer in production.
