fit on the non-magnum receiver? Probably. WORK?? am not so sure. I don't have any to test, so I can't say with certainty, but remember that the 3" shells are not identical to the 2 3/4" shells and more than the barrel needs to have the clearance to handle 3" shells.

Cartridge stops, lifter, bolt travel, ejection port, and probably a couple other parts I can't think of at the moment need to be able to handle the longer shells.

Gas system might be an issue as well.

I don't know but I suspect that if all it took to change a standard gun to a 3" magnum was just the barrel, why would they build and sell entirely different guns for 3"??

Somehow, doing it just to "trick" people into buying another Remington gun doesn't seem enough. I could be wrong, I just don't know.
