This post wasn't about when you bought it; it is about when the rifle was manufactured. The box end indicates the actual model number as will the "Find My Rossi" link on RossiUSA. Rossi has always been very slow on updating their database, but they can find it via a phone call to 305-624-1115.
The switch from Amedeo Rossi to Braztech began in 2008, but the R92 was not reintroduced until 2009. Between that year and 2016, model numbers were very consistent, and you will need the lookup (web-based or phone) to identify the actual model year. The 2016 list below is included as a "base" reference for the change in what had been standing model numbers. Again, my inquiry is specific concerning 2017 and '18 model availability.[hr]

Thinking off hand, I believe we have had one confirmed report of a 2017 model, a picture of the receiver marking, which showed that the year model.
