Is there any 1-cell extender for 18xxx cells?

[who]

I have C2 and M4 bodies that have been bored out to take 18xxx cells.
Is there any 1-cell extender (Ex: Light hound Detonator..) out there that can accommodate the 18xxx batteries.
I have some 2x18500 and 3x18500 setups in mind. Thank you for your help.

The Detonator does NOT fit the 18xxx / Wolf Eyes have some 18xxx extenders (don't know if they have same threading as SureFire) :candle:

Thank you SolarMan,

I knew about the Wolf Eyes extensions. At around $10 a piece, they are excellent values. They most likely would not fit SF.

I might just buy the Wolf Eyes M90-13V-150R Rattlesnake for the 13V light bulb.
