I believe you got one of the original 700ML's. It appears to be a 24" barrel versus the later model 26" barrel. That rifle really is a well done and strong ML. With that said as much as like my Knight rifles this is a better purchase than the 52 in my mind. I really do wish Remington had stayed with the ML's a lot longer. Doing some research I think you will find that is really an excellent barrel.
They really do work well!
