Aleph switch action is a little uneven on the UBH body. There is a little ridge just inside the tube, that I think 'catches' the switch and makes "high" activation sometimes troublesome. YMMV.

OK, this may be a design issue, then, since I've seen it and at least one customer of mine using a UBH has seen it. We worked around it by using a smaller o-ring on the McE2S module, but to really fix it you need to re-bore the tailswitch end of the body.
I say design issue and not flaw because the UBH apparently works just fine with OEM surefire switches (Z52 and Z57). This difference, while not significant with the SF switches, obviously IS significant when using the McE2S. The UBH predates the McE2S by a good while, so it's hard to assign too much fault for this, but if the UBH actually had the same geometry as the SF bodies in the first place, this problem wouldn't have come up.
