Can anyone remove a mauser barrel??

I have a rusty Mauser that could maybe be salvaged with a new barrel. Anyone have the means or know a good technique to get a rusty aftermarket barrel off?

If its rusted it's a bear. You need a special wrench with a fitting to hold the receiver without bending it and a barrel vise to grab the barrel tightly without gouging like crazy. Usually you need to use rosin to stop the barrel slipping.

The end of the wrench head is threaded for an extension bar, which you'll need if rusted, or you can slip a pipe over it.

All in all its easier to pay someone. And you'll need to headspace the new barrel. If its too loose you'll have to pull the barrel and cut some threads and finish ream. if too tight just finish ream. Plus if the new barrel already has sights they probably wont line up and will have to be redone.

buy some Kroil and soak the threads

In the days of the old west a 6 shooter was as common as cell phones are today and just annoying if they go off in a theater.

heat receiver ice the barrel (after kroil or pb blaster treatment)
when applying kroil to threads area tap withnylon hammer will aid penetration unless you dont care about the barrel and use steel hammer

You might as well take it to a smith. I've seen Mauser barrels that were so tight I had to cut the shoulder off in a lathe, and STILL use some love taps with a mallet on the action wrench.

Since you'll have to headspace it anyway, its easier than risking damaging/twisting the action.

The barrel in there now is an aftermarket replacement, but there is no marking or caliber designation anywhere. I've oiled and disassembled it, the receiver and everything else is not to bad. The barrel could maybe be saved, but not knowing what it is, I figured it would be less hassle to change out the barrel.

I will kroil it up for now to try and get some penetration and see what happens.

You could do a chamber cast with Cerrosafe or have a local smith do it for you, would be cheaper and that would tell you what caliber it is. Butch
