someone mentioned a lightweight MRC, which is kind of an oxymoron.
I think that's about right.........

Though they carry a bigger price tag, the High Country Series are listed at 6#2oz for shorties and 6#7oz for the longs. IIRC the different names in this series only refer to different color combinations of the stock and ceracote. That said, I think that's pretty light. I think a lightish one could be built cheaper than the $3500 they are asking for that series.
