I would agree that it's rare to see a factory one in BR, and you see less with custom barrels all the time. Most that are out there have had the barrel changed. I figure there's a few reasons. One is lack of closing cam. For the other, you need to slug the barrel (factory). It's a wonder they shoot at all, but they do. But it's a great action. Simple and effective. And they have a great trigger. Even if you get one of the older ones you can easily retrofit the 5071 trigger, which is the 5018 for older guns.
