The gun does have the micro-rifling. Did Marlin make the barrel for these? As I mentioned earlier, I have another FN with that style of rifling and it shoots really well. Really likes nosler partitions and hornady 220gr RN. I've not shot this one because it belongs to a friend. I'm selling it for him because he has a sick family member. I don't think he has shot it either. Also, I measured the LOP. It's 13-5/8".
