Default Win. Model 12 barrel assembly

I came across a barrel and forearm assembly for a Winchester Model 12 16 gauge. I thought it would be nice to have an extra barrel for my Model 12 so i am thinking about buying it. What work is required to get this assembly to fit my shotgun. My gun is a proof steel gun from the late 30's while this barrel I found is an older nickel steel assembly from the mid 20's. Tell me what i would have to do to get it to work on my gun and how much it might cost. Thanks!

It is hard to say. You might get lucky, and it fit right on, or it may require minor fitting. Unfortunately, minor does not mean cheap. A really good gunsmith, that could be trusted with a M12 is probably going to run close to $100 an hour. When I refer to a really good gunsmith in this case, I mean one who will fit the second barrel to the frame, not the frame to the barrel. Please do not ask why I know this is important.

I once owned a model 12 that came with two sets of barrels, both numbered to the gun.

if your model 12 is also 16 ga,should not be to hard at all. any compotent gunsmith should be able to do the work at little cost. Depending on your experience you might be able to do it yourself. i have a shop manual for the model 12 and this info is also in brownells book Encyclopedia of modern firearms.

good info at this site:

Check the chamber length before you buy it. The older 16 gauge barrels were chambered for 2 9/16" shells, not the later 2 3/4" length. If it is the shorter chambering it could be reamed out by a gunsmith but it will add cost to the project.

Don't ask me how I know.

Most of the above is absolutely correct. The barrel is easy to fit to the receiver as long as you have the set of barrel bushings you might need. It could be any one of about 6 different length bushings. That's like saying it's simple to fly on up to the cool ol' moon...all ya' gotta do is have a space ship. The kit, if you need it, cost around $200.00 these days {if you can find one for a 16ga.} Then there's the problem of possibly having to have the barrels chamber reamed to the chamber ring in the action. Yep...about one fourth of the chamber is a ring that screws into the receiver...the rest of the chamber is in the barrel so they are reamed together at the factory when the gun is made. The chances of having the new barrel flop right on and line up with that chamber ring in the receiver is right up there with Michael Moore ceasing to be an idiot. Again, it's all simple if you have the tooling. The reamer to align the chamber ring to the barrel is special, not just a chambering reamer because you have to turn it while in place with the gun together once the barrel is fitted to the receiver. That reamer is driven or turned by a bar thru the muzzle end of the gun...again not stuff the average gunsmith is going to have. Simply fitting the barrel assembly to your receiver is not hard and it will probably even cycle and chamber the shell but when fired it is almost certain to be stuck hard in the chamber and not extract until that chamber and ring get align reamed.

Thanks alot anyways guys. I found this barrel assembly on Ebay and bid on it, but my bid just wasn't enough. It went for well over $300 and I just didn't want to put that into it and then have to pay even more to have it fitted to my gun. The info. was much appreciated, who knows, I might find another one next week??
