there is a little metal cap which is screwed on with tiny little machine screws that slides under the nose cap. i don`t imagine for a second that it is not important, as it protects the wood from the nose cap. I reused the one that was on the front hand guard i had, but i would think there is a place to get them or get them made. i will be attempting to make one, as i will be needing one in the near future, and will of course show off a successful result. as a hobbyist metal worker, i don`t think it will be that difficult.
