One of my good friends brought one of his recent gun show prizes (VZ/24 in 22-250) in to be rebarreled. I pulled the barrel & low & behold look what I found. Who ever did this must be first cousin to the guy that did the one you are working on.


The smith threaded a bushing ID to fit the small ring barrel then threaded the OD to fit a large ring Mauser.

Oh, a chamber insert... Haven't seen one of them in a long time. This one of yours required a bit more talent than the one Jim described.

Thanks for the picture.

I have seen receivers bushed, but usually after correcting a botched factory thread. I have never seen a bushing to use a small ring barrel in a large ring receiver.

In the 70's/ when cutts compensators "went out of style" and model 12 Winchesters started to increase in value an guy in town cut the barrels behind the cutts, threaded them and screwed on the end of a barrel with a fixed choke. I watched him do this with a 13 inch South Bend and a spider in the steady using single point HSS in a lantern tool post. He even soldered on those oval posts and put a new rib on. With polish and reblue, it was very very difficult to see the joint. It was not all that complicated, but it did require good technique to thread both sections and get a good butt joint.

Some may not like the idea of this bushing, but I think this shows some reasonable machining skills.

I have to admit that I have toyed with this myself just havn't done it yet.

Some older Gun Parts Corp catalogs had some small shanked barrels they they advertised would be perfect for "sleeving" like this.

how big a problem is it, safety wise, hell everything-wise. I mean is it the kiss of death like the "two washers" thing, or is it OK?

Chamber Insert? Looks like a bushing job to me.

I got the impression somewhere that some of the A&B barrels were sold like this. Could be wrong. Is it an A&B by any chance?

About 6 or 7 years ago, a customer brought me a Mauser action and one of the early A&B barrels to install on it. It was set up with a bushing just like the one you've pictured. I talked to a Midway rep about it at the SHOT show the next year. He confirmed that they did sell some set up that way to clear out old stock threaded for I-don't-know-what. I haven't seen one since.

Of course it is, but, have you ever pulled a barrel and found that someone had installed a threaded insert that was chambered to a different caliber than original? I have, and they look just like that. Whether a threaded chamber insert or a thread adapter, either would be more difficult to accomplish than that work Jim had described.

looks like it would likely lead to all sorts of problems in the accuracy dept, just get a different friggen barrel

I have done a couple of these (on my own barrels but no Mausers) and they work just fine. I call it an outsert. If done right there is no safety concern. I usually use a LH thread so there is no chance of the thing unscrewing during firing although that is probably overkill on my part.

Having said that, I clearly mark the barrel so a future owner will know what it is.

Perhaps it’s the photo, or my eyes, but that appears to me to be a chamber “insert†not a threaded “outsert.â€

Does that happen to be a barrel that has been relined by chance?

When I was experimenting with a lot of wildcats After talking to P.O. Ackley about it I did the bushing thing a few times to save money on barrels. I would turn a sleeve and thread both it and the barrel and then use that low temp silver solder that Brownells had in the bottle to attach the bushing on , I guess you`d say, permantly and thread to the larger 98 threads. I ran some pretty stout loads through some of them like the 6.5/06 etc and never had one come apart or swell the chamber. Ackley said he had done it a lot so I figured if it was good for the old MASTER it was good enough for me! I`d NEVER do it on anything but my own stuff of course but it does serve a purpose. It`s a shame to get rid of a barrel if there is life in it.F. DeHaas has a whole thing about doing it on the older guns too.

Aloha, Mark

The barrel is stainless & it is fluted. No markings. No liner. No chamber insert.

I was fitting a barrel on my BR rifle onetime and got interrupted by a phone call. I some how lost track of my cuts and turned the tenon too small. I made a bushing, like the one shown in the pictures, and then fitted the bushing to my action. It shot fine and I used it all season. I have never seen, much less, installed a "threaded chamber insert". I have fitted threaded bushings on Ruger 10-22 barrels and then threaded the receiver to accept the theaded barrel.

Your description sounds exactly like the .220 swift barrel I put on my lowbucks mauser. A&B barrel, with the "outsert" to fit large ring 98. Stainless, fluted 24" long and short chambered. I think Midway had 'em on sale for around 50 bucks. Darn thing shoots pretty good, .5 inch with H380 and 50 grain pills, when I do my part.
