If you contact CDNN Investments (look up their webb site), they had brand new Mauser actions for sale in the catelog I had, for $400 or less, and I believe it said they were flat tops, though not sure that's important these days, as everyone make bases that will fit these actions. I belive CDNN is at
www.cdnninvestments.com, but if you put CDNN gun sales, or some such in the search engine, it will bring it up.. They have some real good prices on things, and they had a Rem model 798 rifle in the catelog for like $400 maybe a bit more, but would be a BRAND new mauser action, made for Remington.
