Wouldn't really know but I thought you could just take the body shroud off? Or do you mean the shroud with the arrows? Or the bottom shroud? I think the bottom shroud is what gives the saber character, seen a Mantis without the top shroud and I think it looks better, then has a nice choke point.
The neck shroud is the silver part with the arrows.
The body shroud is the black/red/blue/longer silver part (depending on which Mantis you got).
The body detaches from the curved part, and the shroud comes off of the top.
Except the speaker mount keeps the body stuck, so the shroud can't be taken off.
And I do like it, but I want to use this saber one-handed, and it does add a little weight. I already took off the neck shroud and replace the pommel and the hilt was noticeably lighter.
Also, I have some plans for the saber. I'm gonna replace the emitter (it's nice, but not my thing) and add a PVC shroud over the new emitter. I'm also gonna wrap the body (the actual body, without its shroud) in faux stingray skin.
