Lyric discussion by wozzock 

Cover art for Gunslinger lyrics by Avenged Sevenfold

the lead singer when he performed it live actualy said about the iraq war and how their is men and women fighting for our rights etc so it is about the war

and it is also meant as

Guns Linger - he went to war [he didnt but hes talking bout it] and even when not holding a gun he is reminded of killing etc shooting

it is a very very powerful song

I've always thought that too
