How to identify manufacturer of BCG?

In particular - I’m trying to make sure my LMT has an LMT BCG in it. thx-c

(I recently purchased a complete LMT from a vendor not on this board to save a buck :frowning: ,that I have since read is of questionable integrity and I’m having my doubts as to the authenticity/origin of the BCG in the rifle)

Does the BCG have any markings at all? I’m sure Grant could answer your question without too much trouble. Hopefully he’ll chime in soon.

A pic of the bolt and bolt carrier is especially helpful in ID’ing it.
