Have you ever seen an A2 upper with a keyhole forge mark with an "F" apparently punched into the metal above (and sort of over) the keyhole or anything similar?  Is this FN or someone trying to fake it?

That's consistent with real FN equipment.  I have one that was certified as real FN gear by a mil amorer.

Thanks.  It just seemed out of line with most other uppers I've seen - low relief vs. high relief.
