A few years ago, FN closed the old plant where the M70s were being made, temporarily ending the line. They tooled up again at the Columbia plant for 2008. The new trigger is supposedly better than the old. Also, the workmanship is back up to par for Winchester, and they've traded in the post-64 push-feed action for the older controlled-feed style.
Disclaimer: apparently the work at the old shop wasn't universally bad, it was just uneven.
For the 2008 series, they used fancier wood, but for 2009 on, the wood is more in line with what you'd find on a sweet rifle that just about kisses the $1000 mark.
That being said, I was under the impression that the Classic was a controlled-feed variant they launched sometime in the '90s. Anyone know if I'm right?
I can't tell you if the MOA trigger is any better than the old one, as my 2008 M70 is my first rifle. I can tell you it's a fabulous piece of work.
