ACOG for 20" A4 Upper?

[rct442]

I'm looking for another ACOG for my new 20" A4 upper, and I was having trouble finding one designed for M16/AR15 length barrels. Most of the .mil ACOGs are for 14.5" M4 barrels.

List so far:
TA31RCO-A4CP
TA31-G
TA01-LAW

What kind of ACOG are you guys running on a 20" A4 upper?

I don't have a 20 inch yet but I have thought about the same thing and based on personal choices about color and reticule I would go with TA31 RCO-A4CP. Because I like the red chevron and I prefer fiber optic and tritium.
