As per the request, this is a closer look at the MHS components of the Catalyst and a look at the MLS unit

I hope you guys find the information helpful
Sorry about the battery bit; I couldn't get the leverage with just the one hand plus hold the camera straight... but, yeah, the way I've wrapped the batteries makes it super easy to get out, but only if you have two free hands

Anyway, here's the technical text, and just leave your comments about how the MLS unit is different (I'm quite interested) plus any other comment you have

MHS measurement details in text:
(components are directionally
male or
female, and the length added to the saber is given to nearest 1/2 cm **inches are guesses, and my be off by 1/4"**)
Threading = 1 cm, which will be lost when screwed into female endPommel (m) = 3 cm (1.25")
Emitter (m) = 5.5 cm overall (2.5 of which is the crowning) (2.25" and 1")
Choke (f/m) = 6.5 cm (3")
Hilt body (f/f) = 18 cm (7")
