<<<do they recommend barrel break in on the bolt gun.>>>

Barrett replied to my e-mail:

"Your rifle would have been cleaned after it was tested fired here in our range. Page 6 of your manual help with break in procedures. If you still have questions please feel free to email me back".

I get to handle ours tomorrow, my dad picked it up and its with him now.
