I see them asking $400+ here. It's a nice, well made rifle faithful to the Hawken rifle design. The lock appears sturdy and well made with a coil mainspring. It is machine made and does not have the subtle lines of a hand made stock. I have not fired mine. I have never heard anything bad about them.
Depends on condition and if it has the box and papers. I would say a minimum of $375-$400 for a decent condition shooter grade with no box or papers. Could go up to $600-$700 NIB with all the paper work.
