Trying to make a Custom Armor System for a RTS

Hello I have been working on a RTS but running into a problem. I am trying to figure out how to get my Static Helmet Meshes to work on my unit. But so far they are not spawning in. Here is the Code I am using. Also I have another question for how to Create Classes for Armor and Weapons, so the variants can be based on there class types i.e. (Weight - Light, Era - Dark Age, Faction - Greek). Thank you for looking at this hope to hear from you all soon, Have a great day.
