M1A/M14 as a SHTF/TEOTWAWKI Rifle in Firearms Posted May 15, 2013 · Report reply Thanks. I think I should save up and get an ACOG. I was in the army for a short while so I do know how to use one. I just could of sworn the one I used needed batteries. But, that is exactly what I need, something that can get to about 3 to 4 times zoom with good close range target acquisition. The price is a little steep but probably well worth it. Thanks again.
