Hoping that I’m using the correct terminology.

I currently have a couple Surefire 640DF’s and would like to get a white and ir head (vampire) for it.

I’ve looked though multiple sources and either I’m blind or they don’t exist. I have a vampire head for the 600 body but it doesn’t fit the 600DF body due to the wider diameter.

Figured i would ask here before i go to plan F.

Anyone seen such an animal and if so where?

Nope, Surefire does not yet make a vampire head for the DF/Turbo series bodies.  

Yep.  I doubt SF will ever make one.  I’d think the main draw to the 18650 setup is the ability to use super high output heads.  Vampire heads aren’t that.  

SF would need to upgrade the existing heads before I’d think it would make sense to sink any costs into developing DF Vamp heads.

Just get a new regular Scout body.  Both Surefire and Arisaka bodies aren’t all that expensive.

Thanks all for your responses.

Always better to check and get others insight.
