Zeroed in my iron sites at 50 yards. Started a bit high but got it down to the last few rds

Nice...I experience the same thing with my sport. It was way high at 100 so I moved to 50 and zeroed it.

With the 0-2 sight, I hope, and by turning the front sight post.

I highly recommend shooting at least 5 round groups when adjusting sights for zero; I always shoot 10 shot groups for sight zeroing or accuracy testing with my AR.
