Even if it had been zeroed before in that config, just the slightly different seating of the parts is likely to throw the zero off a couple of mils.

The barrel and the upper receiver are one assembly.
Thereforethe optics and the barrel are one unit. No change of zero for them.
There is the fit between the upper receiver and the lower receiver that could come into play.This slight and there is available a silicone wedge that can be inserted to remove all play.
A SOF unit could have certain M16 lowers "bedded" to matched uppers. However the silicone wedge is more economical and can be applied in the field.
