I just received the X2000 18650 from DX. The sliding mechanism is very metallic. I want to change the metal ring to an o-ring. Do you guys know how to take the pill out? On my MXDL SA-28, there are two points (holes) where I can grab on and unscrew. On this X2000, there's no holes to grab.
try unscrewing from the front :)
I'm looking down at it from the top. There's nothing that I can "grab" onto and unscrew it.
