I am thinking of getting one of these as my next saber, already saving up, bummed I am going to miss the Halloween sale, what great bargains!
i am thinking of getting it with a Manticore emitter and using the emitter part of the catalyst as the pommel. not sure it will all work out but it may be worth a try!
While this will work for sure, you won't have the lense in there with the Manticore emitter.
Because of the dimensions and build of the Catalyst, it doesn't have the typical MLS unit and its casing in there.
The lense is mounted in the MHS emitter and the LED units sits in the top part of the "choke point" right below the emitter.
Perhaps it would be possible to fit an MLS unit in there if the upper end of the neck would be longer, but am not mechanic so...
