Here is a marine from the book I'm writing called the green string you can join the group, "The Strings of Power", if you want to learn more about the story. To make his visor I cut a clear blue motorcycle visor (trust me this was hard to do with a pocket knife) The guns I made by cutting pieces of of a sniper rifle and a pistol.

With visor up and boot pistol out (The holster can hold his boot pistol of his other gun)
