I have the Mk6 Ilum CMR 7.62 on my new ECC.
at 1x, the dot for me is very bright. As EAB said, my head has to be in the correct position to see through the glass with full view. It's definitely not like Eotech or Aimpoint where you can move your head around and still see the dot/hologram.
The stock for me has to be more extended than I would have for my SBRs.
Once I established the position with the stock, I can reliably and repeatedly see the dot when I shoulder the rifle.
I would give it more time and practice.
