I recently contacted an ebay seller who is selling a ton of these used weapon lights to see if I could purchase an "extender" to upgrade my 6V light into a 9V assembly.
He was able to assist me for this part for about $33 including shipping to BC.
I was so impressed with this sellers service because of his prompt response, but what blew me away is that he threw in a "mount" assembly for the above price!
Anyone with any experience with Surefire would probably appreciate the ability to convert you existing 6V into a 9V assembly for a great price. Upgrading your 6V to 9V also allows to uprade to a Turbo Head assembly for extended range.
Here is his link if anyone here is interested
