I know that other than the V2's the inner diameter is the standard 1.25", and the chassis disks will work, but I am trying to avoid wiring in a recharge port req'd for the 18650's, I'd rather deal with a rechargeable single cell Trustfire. I believe they say 5" or better on the TCSS site, but I'm almost positive I've heard of someone using the V6 sled.............. thnx for looking.
Happy Sabering And May the Force Be With You All Always.
There are some pommels that have a hole for a recharge port, that might be something to consider (I assume you were hesitant due to the daunting idea of drilling and tapping a hole in the hilt).
