It seems to me that there is a lot of wailing and gnashing of teeth going on over the asthetics of a fairly inexpensive field grade rifle. What do you think drives the 2x to 3x cost difference between Marlins and something like the Mirokus? Mostly fit and finish, which often requires human hands, and is expensive.
If a $400 rifle functions and shoots well, who cares if the stocks are a a slightly different shade? If the answer is you, then you have a couple of options 1) sell the Marlin and buy something much more expensive that will meet your asthetic requirements... Pretty costs. Or 2) open up the old wallet and buy some replacement stocks for your existing gun that are up to your standards.
Me? I would be pretty happy if a $400 .45/70 lever gun operated smoothly and was reasonably accurate.
