Good morning.
I have an SKB 12ga model 100 non ejector with 30" barrels. I found a set of 26" model 100 barrels for sale. Are SKB barrels interchangeable? There isn't any wear on my gun or the 26" barrels.
Thanks,
Bill

Not factory interchangeable in my experience. They may require fitting, from minor to major. Kind of luck of the draw. But you should give them a try and have them fit to your gun. It is not that difficult in many cases and not that expensive. But don’t let any hamfisted moron do it. It can go wrong if they don’t know how to do it.

Good advice given here which could be said of any make of gun & barrel fitting. These aren't plug & play mechanical devices. Even in these days of CNC precision machining, the manufactures of SxS & O/U guns still do a lot of hand fitting to get things just right.

It’s the fore end fitting as much as anything that I hate. But I also hate fitting new wood for a fore end so maybe it is me. Sometimes you just get lucky and one fits both barrels. Rare in my experience. It is far simpler to fit or better yet already have the fore end for the second set of barrels. I did make the mistake of trying to use one metal for both barrels and ended up with one who was loose on both. That sucked. Ended up refitting it back to the first barrel and finding a second fore end to fit the second barrels. Measure three times, take just a slight amount I’d metal off and measure/smoke/file or hone slightly.

Fitting barrels properly is tedious enough. Making one forend work with two sets of barrels takes that time and skill to the quantum level. 'Smiths who can PROPERLY fit a set of barrels to a doublegun are not on every street corner. Learning that truth was costly for me. It is a skill that I want to learn for myself before leaving this mortal plane. Having tried and failed at it, I am now even more determined.

There was an excellent article in a Shooting Sportsman magazine some years ago, I believe by Vic Venters, that was titled "Jointing on the Circle", AIR. It was by far the best piece on the subject I've ever seen. I have lost track of it, but may just dig through all my old copies, this rainy day, until I find it again. It is well worth the effort.


This is just my opinion, for what it's worth, but building a gun that has interchangeable barrel sets is not beyond the capabilities of CNC manufacturing. The Thompson Contender break action is an example, with it's interchangeable barrels in different calibers, and it handles chamber pressures many times higher than any shotgun shell.

Thanks for the input gentleman.
