The Mule heads shown are made with Aleph compatible dropins in mind. McGizmo's work, the Sandwich shoppe sells some, and Datiled sells some here from time to time that he builds.
Yes it is! Light weight, small, deep pocket carry, stealth look. It's really a great option for those who have a extra LE, $35 for the body and around $40 for the empty head. There is a bare Al version also listed.
Ooh, that is nice Ben! Now that I have an extra MDC body laying here I am tempted to do something like that and get a VME head for it and a M31L or something. That would be a really handy little single mode long running tasklight.
Did you see what I did to my work EDC McMalkoff Lego? I heat anodized the Ti McClicky pak to look like a flame. I think it looks pretty rad now!
