The barrels will interchange but quite often any sights or bead do not index properly. I found this issue installing a short Norc barrel on a Wingmaster.
I agree expect a slight indexing issue even though most people don't seem to notice it.
Here's a picture of what poor indexing look likes between Chinese clones and Remington's.....
Norinco Barrel on an older Remington receiver...... I doubt there are many people running a Remington barrel on their Norinco receiver.
Not that it would matter the issue would be the same.
The Remington 14" barrels have a pedestal under the bead that raises it up higher.... the Norinco's also benefit from a higher bead or pedestal but the importer's leave that up to the end user to address.
