Is the threading on the back of the Nitecore SR3 head the same as a Surefire E-series? I'm primarily concerned with whether the parts can actually thread together, not with whether the contacts line-up perfectly once assembled. If the contacts leave too much or too little room for the battery, that's easy to fix either way. I just want to know if the parts will fit.

Nope, the E series threads are too small for the SR3 head. The SR3 head will cup on the E series heads but it won't screw down or make contact (good contact).

Won't fit a P/C/Z series light, the diameter of the SF threads are too large for the SR3 head.
