There is a model 14-6, which is the heavy underlug model 14 too, on gunbroker right now. There is only a couple of hours left if you are interested in trying to get one. They don't come up very often for sale or auction. This is only the second one I have seen in at least a year. this is at 12:44 hours mst on 8-10-14.
I do agree with trying to keep everything the same with all your guns for consistency and familiarity.
