Budda- I have one on the way to me, but for a fellow member here I was able to drill and tap two holes and mount a Ti McGizmo clip... I'll see if he will post a picture if you'd like.
It was supposed to be released with an OEM "clip-on" clip, but this was later delivered separately for some shipments. However, the tail is already drilled and tapped with threaded holes that perfectly fit the Nitecore EX11 "screw-in" clip.
I have both, and greatly prefer the latter (in titanium ).
This is my RRT-0 R2 with the Nitecore D10 clip and HDS bezel.
OG holes were not going to grab much material on clip, so I tapped two other holes. I did not use the D10 backing plate, just the screws. I dont EDC this much i have not noticed the screws become loose I have Loc-Tite if it ever does.
