Don't let the haters hate. ACOG is a great optic. Very versatile for hitting targets out to 800 yards or more. Super clear glass. I have a lot of variable scopes and an optic that goes down to 1x has its place too. But a gun you can grab and go and be confident for anything from 100-800 without even thinking, the ACOG is great and fast.
I agree (TA31F owner myself).
