I think they use Lr-308 for several different barrel lengths. I have a plain LR-308 that is 24" stainless. I have saw a LR-308B which was an 18" teflon coated bull barrel. The LR-308L I think is 18 or 20 with a skeletonized stock.
Nice gun. I've got the LaRue mount and a SS 10x40 on mine. The Nightforce will certainly do a better job if it's going to be a dedicated long range tool.
...and a picture about 30sec. before I painted it.
