A lot of units used electric pencils to write the Ser# on the bolt/carrier - it served as an accountability issue, remember the pictures of an AR-15 Semi-Auto Carrier, and a C7/C8 Auto Carrier, and how they where parnoid soldiers where going to swap bolts in the early days for the C7...
Personally have been on the receiving end of extra's for a dirty bolt, I prefer matching, as it ensure that some one does not go shopping for a clean bolt and screw someone with their dirty one.
Also for a purely lifespan wise outlook, bolts and barrel extensions will wear together to a certain point to mesh. If you keep swapping bolts, you really do prematurely age them when you swap them.
Yes they can be swapped, but they really should not be unless its an emergency.
