I saw an M14 at a gun show that had a reciever made by Rocky Mountain Arms. It was stamped on the left side and said it was made in Longmont, Colorado. Anyone ever hear about them? No marking whatsoever on the heel of the reciever. The vendor said the builder of the reciever did it on a CNC. And he made several. Just from the little bit I saw of the rifle, it was machined pretty well as far as appearances. And the builder has shot it several times. The vendor was asking $1500 for it.
