Some rifles even spot weld them I was told. Whether that is true I can not say. I know when I was talking to a technician at T/C one time about removing the breech plug, he told me under no circumstances should I attempt that. Which was good advice. I took it to a gun smith and he would not do it either. So I still have that barrel.

The funny thing is I lapped that barrel and it actually turned out to be a good shooter.
