    MOE handguards on one upper and standard plastic ones on the other, but I zeroed resting the mag on the bench to avoid any POI shift from a rest touching the handguards.

    Before trying the Aimpoint on the second upper I would have guessed it'd be within about 2-3 MOA, but I didn't really have any basis for that estimate. That's why I was a bit surprised the zeros were so far off.
