IMHO, if the rails or mounts are parallel to one another I can't foresee any detrimental effects. The rings will naturally align to the scope body but if the mounts aren't parallel to each other, then when you tighten the rings to the mounts, there will be a fight as the mounts try to align the ring bases to them, instead of the scope body. Don't take good workmanship for granted. I've wrestled with several rifles which had base screw holes either pointing slightly in different directions or worse yet, one is not not true to the barrel centerline. Either way, you're in for a fight when those QD levers get tightened down.
In the case of rifles (or slug guns) which use a picatinny rail, the odds of the rail sides not being lined up and parallel are slim. The biggest risk lies with rigs that have separate front and rear mounts.
