I was browsing on GB and happened upon some pretty cool parts. I know it is just cosmetic, but it is still pretty cool I think. I found several lowers that have the fire control marked "SAFE" and "ZOMBIES" and another one marked "DEAD" and "UNDEAD". There are chamber covers and uppers marked "ZOMBIE KILLER" in various ways also. Maybe they have been being made for a while and I just didn't notice them. It would be pretty cool to have as a lower for my 458SOCOM. These AR's really are moving way outside of their original intended use. There are more custom options available than you can shake a stick out. I guess it really is true like they say, "AR's are like Barbies for men".
