They make a TOOL for removing the barrel on 760-7600-6 Rifles.
I've never used heat to remove the barrel. And I don't use loc tite to reinstall them. They are firmly attached and need to be RE firmly attached. I use a short 2x4 to bump the tool handle to loosen. Conversely, I BUMP the handle to RE attach.

That's a neat looking tool. I just tried searching for it. Brownell's came up, but when I search the site, they don't appear to carry it.
There's a video on disassembly here:
