I got my 1895 in early 2006. It had most of the problems that this man experienced - two lands have chatter marks over the last few inches, weird discolorations on the bolt and inside of the receiver, nasty tooling marks in the receiver, etc. It works and it shoots, but I was kind of frightened when I first saw it.
This problem didn't just start when Remington took over. IIRC, this was right about the time that Winchester went under. I recall a Marlin rep at Sportsmans Warehouse explaining it to me like this: if you wanted a lever gun for under $1000 during that time period, it was Marlin or...well, Marlin. They stepped up to meet production and quality unfortunately began slipping.
When I heard the news that Remington bought them out, I wasn't happy. I don't recall a product ever becoming better because Remington took over. But there were problems before that happened, make no mistake.
And to the producer of the video: if they did indeed sabotage the tooling prior to the move, they did it at least as far back as 2006.
P.S. If anyone knows what the heck turned parts of the interior of my stainless receiver brown (it does not clean up with any solvent that I've tried), let me know. I figured it was scale from the heat treat.
