This is what I know. I sent my 308mx in on 8/17/11 and I got her back on 9/6/11. They replaced my 91 serial number receiver with a MR serial numbered one. In the letter I sent in with it I asked if I could have a large loop lever installed, for which I would pay, but they put one on at no charge which I am very happy about. Three weeks was the turn around time. I know that many have had a much different experience, but I have nothing bad to say and would happily buy another Marlin product. The rifle is of the typical Marlin quality I am accustomed to, and it cycles ammo very cleanly. In fact, the action feels so slick, it's almost as though I am getting it back from sending it somewhere for an action job. I won't be able to shoot it until the weekend, but I have to say that all in all I am wicked excited with the rifle I got back and very happy overall with my whole experience.
