Top of bolt carrier "crossed flags" proofmark and "UB" stamped
Top side of bolt carrier "6577944" electropenciled
no other markings anywhere on carrier

Bolt left side "crossed flags" electropenciled in
Bolt bottom "7003222" electropenciled, and "DU" stamped.

It is a sand cut carrier, no other markings anywhere. Hope this helps, Azure
