Take things in perspective. This is a inexpensive brush gun. Not a high dollar shooter, like many Winchester's and Henry's. Yes we can all agree that Remington hosed Marlin quality when they bought them out. I feel that the quality has gotten better in the last couple of years.
This is a good deal on a working gun, something you are going to carry in the woods, not hang on your mantle. Does not have a high gloss shiny blue finish, it appears to be some kind of propitiatory dark parkerized finish. Found an advertisement that stated "The blued finish is protected by a tough Mar-Shield finish." A thread in THR said that it is a lacquer finish that is sprayed on Marlin rifles. I use Flitz Rifle/Gun Wax (same stuff I use on my blued revolvers) on my 336 and it still looks good.
At 150 yards this is dead on. That is the longest shot I will be able to take in the country I am hunting in.
Is the action smooth as butter? Nope, is it satisfactory for a hunting brush gun, absolutely.
For a real sub $500 30-30 I would recommend this gun to a hunter. If your If instead you are looking for flash, try one of those shiny Henry's that are a scratch waiting to happen. If I scratch this rifle I wont cry.
