Dang, again I'm surprised that something like this isn't out. If I can find that 2AA body with bezel down clip whose name I can't remember I'll look for one of those.
jsburley carries similar shroud but without clip. Shroud
replaces tailcap button retaining ring.Easy to attach.
These are made by Valiant Concepts in small batches,
currently out of stock. But, if a bunch of us bombarded them with
email maybe...
