EXTRACTOR:
Who marks their extractors with an "F"?

BOLT:
Who marks their bolt with "MPE"? (Yes, MPE, not MPC...

Thanks,

I have some FN MPF marked bolts & F marked extractors

The "MPE" could be an "MPF" with a underscore (line) under the "F"... as the "E" is slightly larger than the "MP" stampings. Take away that bottom line, the "F" would be the same size as the "MP".

So I guess it is a FN bolt with and underscore mark under the "F."
