Rotate turret base and barrels individually to aim at a target?

Unity Engine
1

So i have a makeshift turret using the Unity primitive meshes and want to have the base rotate only left and right to align with a moving target, and the barrels to look up and down to aim at it but i’m not sure how.

void LookAt ()
    {
       
    }

You can make the turret base and barrel both look at the target and zero out the rotations that you don’t want rotated.

Something like…

transform.LookAt(target);
transform.x = 0;
transform.z = 0;

that would be for the base. You would do something similar for the barrel.
