Has Anyone Taken Apart a Nitecore SRT control ring?

Just got a Nitecore SRT-3, and am really liking the multiple modes, as well as the detent system. The control ring, however, sits a bit too loose in its groove, and can be rattled from side to side, with one corner being particularly mobile (I assume it's the side without the detent). Am looknig to try and tighten things down *very* slightly.

I've seen posts of people disassembling the head of the Sunwayman V11 to repack with grease, but has anyone done something like that with the SRT series? Any tips or tricks?

I've repacked V10R & V11 control rings (without dis-assembly) by hand forcing wheel bearing grease into the control ring area. Lucas Red-N-Tacky grease works well for this. It takes very little extra grease to change the feel of the control.
