Mecarmy Illuminex disassembly help

Hello all

I just received a Mecarmy X4S and Id love to put a Nichia 219b in it in place of the XP-G2 that it comes with.
I can’t tell if the board and LED is press fit in the head or screwed in. Has anyone taken one apart?
Hopefully someone has some experience and hopefully I don’t break my new little light trying to find out :person_facepalming:
Thanks
