I was wondering where the efest button top 26500's can be purchased. They seem to be out of stock everywhere including MR E liquid. It seems like they might have been discontinued. I wanted to buy the efests 26500 flat tops but they look like they won't make contact. Is it safe to just use some spacers on this mod? If so, what size magnetic spacers would you recommend? I really need another set of IMR 26500's Thanks.
