It's just supply and demand . Only 2400+ were made, someone will buy even at those prices. I looked for one for years. I had to build my own and just the factory barrel was about 1/2 the price of a new rifle. HYDE
Sort of new to this forum. Used to gab with you on the old Marlin Talk. I was going to mention that the buyer of the 336ER on Gunbroker might have more of these than you think. This might be his fourth one. He seems to like this model. Seems to be keeping the price up.
