Dissecting my host

I have a host lying around that I would love to use for a 445 or 473 build but I can seem to figure out how to remove the laser module out of it.

This is the host I have (I can't take pictures of mine atm as I'm at uni)

Does anyone else have this host and know how to dissect it?

Looks like a standard repurposed flashlight host. Usually they just twist apart:

Try to post some better (actual) pictures of the host.
