axis replacement bolt

I have a axis less bolt that I would like to use for a project, but getting a replacement bolt here in Oz seems to be bit of a problem. I seem to be able to source all the bits needed from Brownells but not the main bolt tube which I think I can make my self. This leads to my question in reguards to bolt heads and the rotating one behind the front head. Are there any compatable heads from other models such as model 10 ,12 etc?

The Axis uses the short action bolt head, so any short action bolt head will work in the Axis. Same for the front baffle.

You can use the front baffle from the 110 series but it has a guide fin that will need to be sanded down.
