What is the part that pins onto the barrel that the bolt chambers into? I am needing to replace this pined on peice and need to know what they are called. Any help would be appreciated.

This is on the sr25 barrels

The barrel extension? If so, that's not a user replaceable part. Replacing one would be a very involved process, and honestly, probably not worth getting done. What's wrong with it?

They are the barrels I purchased from Chad Dixon on the barrel grave yard thread. He told me upfront that two extentions were not removed because they had cracks. The others were all re-used. So I was wondering if I could purchase the extensions and have my smith work them.
