Adam,

Nesika Bay who made the Arnold Arms Apollo actions in Chrome moly as well as stainless steel are planning to bring them out again. This was a CRF action and they may sell it under the Dakota name as both companies are owned by the same group.

There is a custom riflemaker Stuart Satterlee who also makes these on a one off basis and if you want to contact him, let me know. Stuart also has some titanium mauser actions for sale though these are only in the kurz size.

Good hunting!
