That's what's in there, and it's a perfect beam with a Cree XR-E. I have an XP-G coming in which will be tested it that light, and I'll report. DaCap has already tried it, and it looks good.
I believe that's an Aleph 2 head and tail with a TiN coating separated by a brass body made my the UK's very own custom builder,
CPFer Ganp, who I believe deliberately allowed the brass to build up its own patina before sealing it in.
