I’ve taken a zero. It was my first time shooting the NRA AR Tactical class. I spent too much time fiddling with my gear and ran out of time. Actually it was 2 zeros, my last 2 shots.
At another match, had a guy in the lane next to me cross fire on my target, a perfect center X bullseye. I got his X and he got a zero.
You learn and live to fight another day.
