I just purchased a Marlin 1895 "Cowboy" in 45-70. One of the infamous "Remlins".
According to the barrel code this one was made in October of 2015. Wood to metal finish is very good and the action is quite smooth - as good as any rifle I've had that did not have a custom "slick up" job. Overall fit and finish is more than acceptable. Wood is of a nice grain and finish, and the metal finish is well above average.
Articles I've read on various marlin sites (and I looked at a lot) tend to indicate that the rifles made in 2014 and 2015 are the best since the transition - but the review didn't cover 2016. My guess is the quality will stay the same now.
I guess like all firearms some will be better than others as they leave the factory, but all in all I think Marlin/Remington got past most of the quality control issues they were having in 2011 and 2012. They did have some real quality control issues through there with what was called the "Marlingtons".
I don't have a lot of rounds through it yet but the only thing I've found so far I didn't care for was the silly "Warning" they have stamped into the right side of the barrel. Yuck! But as a shooter it seems fine.
So - all in all - so far so good .............
