Green laser pointer disassembly?

I ran across mentions of using a green laser pointer to point-out stars.
Sounds like a way-cool idea to me. So I ordered a BTG-6 laser
pointer, just like this one but not tuned to 5 mW:

Most websites say the output power cannot exceed 5 mW. But this website
says it's the input power, not the output power, that cannot exceed 5 mW:

What's the deal, what's right?

From what I can tell the BTG-6 has a simple rheostat pot, probably to
tune the output power.

Or maybe it changes the pulse width. Does anybody know?

The bottom-line question here is the best way to disassemble the BTG-6
laser. It sems these guys do it regularly without tearing it up:

Has anyone here done this? Any recommendations on the best way to get
at the PC board?

Thanks for your help.

Never mind, I figured it out. It's pressed in for the final 1/8".
