500Boswell,

You should have a location specified in your profile. State of Australia would be fine.

Mialls probably can give you a quotation as to the prices for the barrels you are interested in. But some could buy a whole new rifle. Pretty standard for the German multi barrel rifle brands though. Nothing is cheap on Sauers, Mausers or Blasers.

Send to me a PM saying what you are interested in and I will try to reply.

The action is smooth enough. Overall I like the rifle, except it is too heavy. Hopefully some of the additional barrels not being "solid" or heavy barrels will feel better.
