Not by any appreciable measure.
The longer sight radius helps at the far end of the rifle’s effective range, but the use of optics (compact scopes or red-dot sights) negate this advantage. And the M-4 is much more compact for somebody in a vehicle.
My son is building an M-16, he bought the lower trigger housing group. I was thinking of doing the same, particularly since we live in California and they’re Nazis here. The A4 version of he M-4 would be nice.
