They came from Yugoslavia. Remington no longer imports them.
Does that mean they were good, and the ones still stamped Remington ar OK but all the others are not good?
None of the Remingtons I looked at (and I looked at a lot of them) impressed me at all.
Every one of them felt like it had sand in the action.
For much less money I found I could buy a good used Interarms that was slick as glass – prices were consistently around $300. In fact, I ended up buying a NIB Interarms Mark X action, A Savage 111, a couple Rem 700's and a couple Rugers instead of the "Remington" Mausers. One of the Rem 700’s was new, as was the Savage. The others were used. In every case I was much happier than I would have been with a gritty “Remington” Mauser.
For what it is worth, The Ruger MKII/Hawkeye design is arguably the best commercial instantiation of the Mauser design available. Smooth, reliable, accurate, rugged, good looking – pretty much the definition of what I want in a rifle.
