I was zeroing it today at 50yds (previous shooting/sighting in was guesstimated) reticle is the ACSS by Primary Arms for the 1.5x ACOG. I love the design and I was really happy with it. On the sixth round, half the reticle went out. Seventh shot and the rest of it blinked out like a light switch going off.

Probably has 40 rounds total through a rifle with it mounted. Fiber optic isn’t loose, hasn’t been dropped

I requested an RMA so we’ll see what happens
