Why the difference, is beyond me.There was discussion about that issue with the last run of Legacy F-3s (probably F-7s) as well. I don't remember the reason, but you could go back and find those threads. Might have been that one end of the B had an electrocoupler which was a different length. Some talked about replacing one of the couplers to even them up.
Didn't they come with a dummy coupler in the box in case you didn't want the 3' gap between units?
Nope. I usually use a dummy Weaver coupler cut down to shorten the gap
Looked in the boxes, all the new ones have a short dummy coupler to replace the long electrocoupler.
