Disney Rey Force FX lightsaber dismantling?

[Barkuti]

This is as far as I've come up in trying to dismantle this thing; blade doesn't unscrews. The plastic red button thing looks suspicious, but since it does not seem to come apart easily I thought it could be better to ask first before I break something. It already comes apart from the back, but not from the front as you may already guess.
Ideas and/or guide are welcome.

Cheers

I was in the same situation a few days ago. I ended up using a saw.

Hasbro or whatever manufacturer used some sort of super glue. I was able to remove the top by applying heat but ended up warping the plastic. Doesn’t look pretty but I got the emitter off without any cutting.

Thanks for the replies.
Definitively not pretty.
I'll see what I come up with. White spirit/gasoline would dissolve the glue, but I need a way to effectively apply it.

Cheers
