Can I inquire where to find one of these please...
I made one from a carefully selected piece of pvc. I think it was for underground sprinkler piping. Took a good of sanding but works perfect.
Here is a couple pics of the tube I used. Takes a good bit of sanding to fit a surefire and less to fit an 18650 body but works really good in my C3 to run 2AA.
