    Model 12 barrels are not interchangeable as they are on a Remington 870. Extra barrels can be fitted by a gunsmith however.

    Some Barrels will interchange and some won't, when you twist the bbl on and slide the forearm down and twist the Mag tube and slide the pin, now try to wiggle the bbl back and forth, the Bbl should not be loose and wiggle above the reciever, it should slide w/ some resistance and be snug when re-assembled completely. If it is loose or won't go together it needs to be proffessionally fitted.

    Replacement of a barrel or reworking a spare barrel for the Winchester Model-12 to allow interchange has a number of details that may need attention to ensure the reliability of operation that you would expect from a fine classic.

    The barrel being tight against the frame is the first detail noted when not present at first trial assembly. Alignment of the chamber to the chamber ring being offset will be the first probable problem noted after firing the first shell. Remember to take your cleaning rod JIC.

    If using a complete spare front end, the magazine tube and action slide (sometimes wood fit, as well) may have their own set of fitting issues that need detailing especially if one or the other half of the gun has been used a lot. Pounding of parts raises burrs that may interfere with fit of parts that were not being mated by that noted pounding action. The issue is similar to swapping worn piston rings and getting bind in ring grooves.

    A Model 12 specialist (such as myself) can rework and refit parts that don't mesh properly, rebuild those parts needing renewed engagement, and refitting or fitting a new chamber ring and barrel adjusting ring.

    My exposures to various unusual problems with some factory-induced issues of Model 12 parts and assemblies gives me insight into particular details seldom experienced by most gun repair facilities.

    One example that I use to show problems of an unusual nature would be to point out the possibility of thread error present in brand new and previously installed barrel adjusting rings that create an offset to the chamber/chamber ring juncture that changes as the ring is adjusted. The worst possibility is having a chamber ring fit at the same time as one of those offset barrel adjusting rings. The chamber mate starts as perfect alignment, and becomes progressively offset as the adjustment is changed. Talk about a creeping issue.

    If you speak to any repair shop about adjusting rings and they are unaware of (fail to mention or affirm) this issue, try somewhere else. I believe that such possibilities should be brought out by the gunsmith early in the conversation, and not be left to chance encounter. I have not seen any one else mention this issue or relate that they had seen this issue, (such as Only Winchesters moderator at SGW) including many that hold themselves out as having plenty of exposure, even if they are not "real" gunsmiths.

    I expect my postings to inform, educate, and relate relevant details and issues pertaining to the subject. I do not intend to belittle others who may have less knowledge about some particular issue any more than I care if somebody corrects or expands on a problem or issue that I may not have had comprehensive data to impart. Go with your strengths and recognize your limits and weaknesses.
