I just received my #40A. It looks OK except for the fact that there's a tiny gap between the upper's top rail surface and the sight base. See the following:



The upper is from a Model 1 20" kit. Should this gap be here, and should I care either way (i.e. will it complicate the zeroing process)? Other relevant facts: I have 2 detchable carry handles that I have mounted to this upper. One, marked "MM", has the exact same issue as this #40. The other, a Colt rifle take-off, fits flush with the upper.

Hey look at this thread - it looks like the gap might be there too?
