I have use a couple with good results. Big thing to look at is the spacing of the action screws. There is one action Style out there commonly referred to as a "J" action and it has an odd bolt spacing of something like 4.52". While the action is just as strong as accuracy capable as any other standard action, however stocks are not as easy to find in the aftermarket world. They are out there, but just harder to find, usually custom built-to-order.
Most of the parts will interchange, most bolt heads will work. Some of the older bolt heads have the alignment notch, but that is a very easy fix. Firing pin sizes vary but that is not limited to the older models.
I would not be afraid of these older actions. The post 2008 actions are supposed to have the best Quality Control during manufacturing, but I think the older pre-'08 actions are still way ahead of the competition.
Just inspect what you are looking at buying, read on here and the answers will present themselves.
