Hello folks, I'm interested in getting an alternate tailcap for my E1B. I know that some people are using the E2DL's cap with the E1B, but does the incan E2D have the exact same cap? If not, what are the differences? I'm wondering if I can expand my search to E2D/E2DL caps or if only E2DLs will work on the end of an E1B. Thanks!
