I'm pretty sure that's an early Mark Worley saber from around 1999-2000. I'd recognize that mating bolt & hollow emitter fins anywhere. Must have sold mine 6-7 years ago, so no pics of it left. Three other distinct tells that it's a MW saber: the small emitter hole, body is too long & has too large a diameter. If you post the measurements & compare to an MR, you'll know.
