I want to label or engrave a couple Shilen SS barrels with caliber etc. I looked at engravographs and a couple Marking Methods Inc products but I just don't want to put $350+ into something to just write on a barrel. So, I'm looking for any suggestions I can get. All I can think of now is buying a label maker and printing out a sticky label. I'd rather have something that is a little more permanent though. Any ideas?

Thanks!
