Google Marlinowners dot com. There's some good stuff on there regarding the marlin 308 express. On that forum, the advice was to avoid the MR serial # ones and the 91 serial # ones, as there were problems with them. I am currently looking for a Marlin in 308 express and there was one that I will probably try to trade for at a gun shop not far from me. I think the otd price was $599, and it is a used rifle, but we'll see.
