If you are looking for some custom dogtags for any occation, I recommend checking these guys out. They won't censor your ideas so the only limit is the space on the dogtag. For those who like to see things first, their website has a snazzy preview mode that gives you a really good idea of the finished product. Many silencer colors are available and metal connection hardware including the fancy braided wire with screwlock.
