Comment from Pierre, the Swiss Products owner.
"Ok. Gents........... First, the group is 100 yards. All of the groups measured 1.2"
I realized that I had run out of 100 yard targets, so......... My Daughter improvised.
My eyes are no longer that great with either open sights or Diopter, so most of you will do better than I did for sure.
That should have been an easy MOA or less. Just too fuzzy for me anymore.
The front sight you see is the new EAS. Unfortunately, I'll have to run another test using the original Type P/S front sight.
It appears to be a good height alignment, but it'll be tomorrow before I can do this again.
The Diopter itself is a definite "go for production."
The k11 will have to be tested tomorrow with a standard front sight, but the alignment is perfect on the k11.?"
