Archived [ARCHIVED THREAD] - upper receiver markings?
Posted: 9/13/2004 12:03:37 PM EDT
Just got two flattop uppers in the mail.  They have two different markings on them.  One looks like an "A" with the top cut off, and floating above the bottom.  (I think this one is Olympic?)  The other looks like a keyhole, with a vertical line of 3 dots inside the keyhole.  I have no idea what this marking means.  Anyone know?  Thanks.
