Non-Milsurp: Winchester M70 Identification Help WHAT IT BE!

[vintage hunter]

I think you mean Short Action, it's a .243 Win. Thanks for the eBAY item number. The reason I was looking at the Boyd id because of their AT-ONE stock, it has the adjustable length of pull and cheek rest at a reasonable price; but I dont see one for the heavy barrel. If I don't go with that then I think I'd be at factory stock just to bring it back to the original configuration.

No. I meant long action like I said. Just because it's in .243 doesn't automatically make it a short action. Prior to the late 80's early 90's there was no such thing as a model 70 short action. They were all the same length.
Standard actions for shorter cartridges like .243 were fitted with a magazine block(Open the floor plate and you can see it just ahead of the middle action screw) and shorter spring and followed. The ejector and bolt stop were changed also to shorten bolt stroke. Distance between action screws will be 7 5/8".
