A Pre-64 vs a current rifle.

Mostly it's the feed lips on the action. How often do you encounter a pre-64 with feeding issues? Unless it's been mucked with, NEVER! Post 64, the feed lips are built into the magazine body (which is how everyone builds rifles these days).

The pre-64's are just uber-reliable, absolute foolproof reliable.

I think the pre-64 action was a degradation of the Mauser action IMO, but it's still a straight up world class rifle.

Regarding the stock...Ergonomically I like it very much, it feels great. But visually it's hideous.
