Taclites M600 Help

Hi I have a Taclites M600 coming from Vinz in Germany to me with one of his P60 drop in’s , but I would like to ask some things;

does anyone know what O ring size would go where the lens is?
also I have not seen these lights with a clip , do they have any, and would a surefire clip fit ?.

anything else?.

thanks everyone.

Bump .

O-ring size should match the P60’s top OD i guess .

thanks , I’ll ask Vinz this.
thanks
