I went to zero an LMT BUIS on my CMMG upper today. I was zeroing at 200 meters.

I had to bring the front sight post up to where the base is above the front sight base.

Is this normal?

Thanks

You holding center mass on the target?

Is it a F marked front sight base?

Mine is, and I'm 3 clicks down from flush on the FSB. However, a Guy I know has a non F marked FSB and his is like You described.

If it's hitting where You aim, don't worry.
