There's two types of co-witnessing.
The first is where the iron sights line up directly over the optic's red dot. Makes it a little easier to zero the other sight once the iron sights are zero'd, and vice versa.
The second is a lower third co-witness, which means the BUIS line up through the glass, but below the Red Dot/crosshairs. Its roughly in the "lower third" of the glass.
I told the new me,
"Meet me at the bus station and hold a sign that reads: 'Today is the first day of the rest of your life.'"
But the old me met me with a sign that read: "Welcome back."
