By that I am assuming you mean remove and reinstall a different barrel.
That will require some skilled lathe work because you have a 1 in 360 degree chance that your replacement barrel times correctly.
Basically unless you have a lucky rabbits foot the barrel will screw on and the sights will be clocked somewhere other than 12 O-clock.
Thread pitch calculation needs doing to determined how many thousandths need to come off, and the barrel shoulder has to be cut back to accommodate (and within about a +- .0005" tolerance)
Then your headspace is likely going to be effed up and the barrel shank must be cut down, chamber reamed, extractor cut re-cut, and oh by the way it will also change the location of your forend and tube attachments.
Then you get to trim down the stock, and shorten the magazine tube.
Thats the short version.
