I'm picking up a LH McMillan Signature titanium mountain rifle with it's titanium action.--very clean rifle. The original titanium barrel (which were subject to severe galling) is long gone.
I'm looking to build a LH superlight and will be rebarreling from the chunky .280 wiseman tube on it now.
Obviously this one utilizes a Micky stock...

I'm wondering if this action is a LH Remington 700 clone? Is it threaded for a 700 style barrel? I don't have it in hand yet, but it looks exactly like a 700 action, hence the questions.

Any thoughts? Anyone own a McMillan rifle?
