What is the best way to get to a component that is common to several classes?

Question

Unity

ItemInfo is used in several classes and carries general information about objects.
Can this code be made more concise?

public void SetItemInfo(ItemInfo info)
        {
            if (GetComponent<InstanceWeapon>())
            {
                GetComponent<InstanceWeapon>().itemInfo = info;
            }

            if (GetComponent<InstanceLook>())
            {
                GetComponent<InstanceLook>().itemInfo = info;
            }

            if (GetComponent<InstanceSupport>())
            {
                GetComponent<InstanceSupport>().itemInfo = info;
            }
        }

Through the interface. GetComponent works great with it.
You can also try using the base class
