I had a request from a client to rebarrel his rifle. I feel a little sheepish asking this, but has anyone done a rebarrel on one of these? I need some info on how the barrel extension is attached/removed.

Jim

lets see - rem 7600 you say - hacksaw?? cutting torch??

No, it was 760.

Jim, it seems I had to do this a few years ago. It is threaded and the lug is a separate piece.

You'll laugh or be disgusted when you get it apart! The extension w/ locking lugs is threaded to the barrel behind the attaching lug, which on the one I just had apart was NOT threaded to the barrel! nYup that's it...half a dozen threads or so to hold the works together. Being the high paid profesional that I am..!!!! I tried a crescent wrench for s&g, figured before I took the time to make a wrench I'd give 'er a go. Was not tight on this one...came right off. Hope yours is as easy to work with.

Jim Kobe.

The early one had RH threads. After Rem had problems with the 742 rattling the locking lug extensions off they then went to a LEFT HAND thread. This carried over to the 760 as the extensions are the same. Do not have access to the barrel date code change off hand but can look it up.

Some are loose as Jim DuBell ran into and others are so tight that you will need to make a special wrench to remove them. This has an section that goes around the extension and a insert that goes into the bolt lug recesss.

If someone runs into one of my old 760's it is a 35 Whelen with a 24" Octagon barrel. I would like to know where it is now.

GunParts Corp usually has used barrels for the 760. I was pleased witht the carbine length barrel I bought from them last year- about $90 with sights.

Jim I am doing one for myself in 338/06. Here is a pic of the barrel extension.



It can be done. The photo is of a RHT 742 extension which is a wee bit different on the bottom than a 760.

Thanks guys, that really helps.

Jim:

You and I find ourselves on a lot of the same web sites. I enjoy your post and respect your abilities. As for your doing a 7600 Remington. I have not done the 7600. I have done several 742s, 7400, and 760. Have you ever done a job you just regretted taking in from the start. That is my thought when I think Remington pumps or Semiautos. They are usually money loosers from the get go. I'll cross my fingers all goes well for you. No twisted actions, No marred receivers, barrels, and/or pump guide rods.
Good luck

One other question while on the subject. The pictures posted show the parts. Is the lug threaded to the barrel or is the extension with the bolt locking lugs the part threaded. If the latter be the case, what type of wrench is used?

Longshot: It would be for a 760, not a 7600.

Jim

The lug is not threaded. It is free wheeling. The barrel/lug extension is the only piece that is threaded. You will probably have to make the wrench. As I recall when I did mine, I took a flat bar of steel and bored a hole through it that would allow it to just slip over the barrel extension. Then I punched a hole through the side so I could insert a pin punch into one of the two cutouts of the extension. Use one cut out (right side) to remove the extension, turn the wrench around and use the other (left side) to install. Kind of like a spanner wrench, but one that completely encircles the barrel extension.
