·I found it necessary to re-torque the barrel nut on one of my ARs so after reassembly I needed to re-zero the Aimpoint/BUIS/laser.
I choose to zero at 100-yards rather than some closer surrogate distance. The problem with getting an accurate zero at that distance with a 4-MOA dot is consistent hold.
So I created a painting stencil that I can use to mark an IDPA target for this purpose.

From the bench using a rest and sandbags I zero the dot by floating the center of the white circle. (I know I need to tweak that zero to the center more but it's close enough for government work.)
Then I confirmed the co-witness with my BUIS.
Because it was overcast this morning I was also able to zero my visible laser as well. I held the rifle on the bags while viewing the target through the spotting scope and could see my laser dot on the target. I then shot and zeroed using this technique.
An interesting feature of this particular AR is that I run a Surefire X400 Weapons Light/Laser at the 6-o'clock position.

When shooting at 100-yards the laser and the Aimpoint dots merge. At any range closer than 100-yards the dots are stacked and one need only bracket the intended POI.

When I want to go all Ninja I simply attach an absorptive neutral density filter over the laser reducing it to NOD levels.
