Bought the Echelon gear up (comes with Viridian rfx11 installed) from my LGS 6 weeks ago. I’ve put no more than 400 rounds through. I was shooting yesterday and felt something hit my cheek, thought it was just casing. When I went to aim, my green dot mysteriously disappeared. I looked down and saw the glass sitting on the table.

Going to the LGS tomorrow to see what they want to do about it.
