Ruger Amerian Rifle Shoulder

Most rifles have barrels that are not intended to be removed. They have a shoulder that tightens against the receiver. Savages don't have that shoulder and use a jam nut. I thought Ruger Americans were the same way.

I see Pac-Nor makes a barrel for the Ruger American. But it has a shoulder and they say a gunsmith needs to turn it to headspace. In fact they say that about all their Prefit Barrels.

So what gives? Does Pac Nor expect you to install a barrels without the nut?

Then I note they make a barrel nut for a Remington.

How does it shoot ?
The M98 has two shoulders and proper fitting means BOTH shoulders tighten against the receiver ! This means full rigidity for better performance.
Many designs are developed for ease of manufacture and lower costs. How do the custom target rifles do it ?

That's not the question. The question is, does the Ruger have a screw, changeable, barrel like a Savage? Or, is it seated against a shoulder where it has to at least initially installed by a gunsmith?

This looks like the barrel has a shoulder that goes inside the nut but bears against nothing.

Kinda looks the same as a Savage, but different
Same principle.
Set head space, tighten nut.

Core of the question. If the shoulder bears on nothing why does Pac-Nor say it has to be turned back to headspace? Do they intend for you not to use the nut and seat it hard against the receiver?

Now, granted, they say that to cover all their prefit's so I don't know if it really applies.

I'm sure that's an error on the part of Pac-Nor, in that the American prefit should be fully chambered- but call them to check.

For shouldered barrels (as opposed to "nutted"), "prefits" can be either short-chambered; requiring reaming the chamber to final depth on installation, or short-shouldered; meaning setting back the shoulder on the lathe on a fully-chambered barrel for correct headspace.
