Like the title says, would you let a ships turret rating be selectable as a component to be damaged by crits?

Considering the fact that a ship is studded with at least dozens of different turrets scattered over all sides of the hull to give as much protection as possible it seems illogical to me. A critical hit might rip of a part of a ship and a few turrets, but can not really be expected to shear all the close in turrets from the whole hull. Furthermore, as rules go, they are a given, not a component. That being said, it makes flak turrets a legitimate target. So, as an in between solution that allows you to degrade the anti-torpedo and attack craft ability of a ship, you could make flak towers a legitimate target for crits and leave turrets out of it.

Nothing in the rules that allows you to.

But turrets are scattered all over the ship as already mentioned. A cruiser can easily have hundreds of them all over his hull. Taking them all out with a lance strike seems strange. Itd mean critical damage on pretty much every single section along the hull after all.
