I have an Eotech 551 that was manufactured 8/03 according to the box and the sticker on the bottom of the unit.  How do I know which "Revision" this is?

Mine has it printed on the EOthing itself, right next to the thumb screw.

nothing next to my thumb screw except "for law enforcement/military use"

Is there a letter below and to the right of the LE/Mil use only?

I think Eotech only started labeling their sights with the revision at F.  The F should be on the sight hood, under the laser warning sticker.  Chances are, you've got an E revision.  I've got a 511 E that was made about the same time period.

I would also guess that it is an "E".
