First, I want to thank J&T for repairing at no charge, my 16" kit I purchsed a couple of years ago , barrel to upper was loose.
I have a question about a manufacturers mark I found while cleaning it. I would like to know who's mark it is. It is a star and is on the end of the barrel or barrel extension, I don't know where barrel ends and the extension begins, just outside the chamber. If anyone else knows please feel free to reply.
Thanks again J&T
