Maybe they signed some kind of exclusive deal to be the only retailer of the refurbed guns. I just called Umarex last Thursday inquiring about a refurb M52 (which they didn't have). As far as I know they, Umarex, are still selling refurbed guns directly to the consumer. Maybe Cabelas is trying to increase it's sales of airguns by offering RWS refurbs, seeing how the price of the (new) European products has gone up recently. The questiojn I would have is could you return a refurb to Cabelas or would you have to deal with Umarex for repair or replacement.
