Harmony gets my vote of those two.

There is a method for getting them saved to the build out of your ship yes. They can sometimes be repaired (maybe only in game looted items) but in my case have always come back with a claim.

If you want to try it out here’s the steps that have been shared and are working for me.

• Retrieve Ship.
• Place Guns on the gun racks of the ship. You may need to leave Armistice zone to place weapons
• Store Ship
• In the Vehicle Loadout Manager, remove a component like the cooler and Save the Build.
• Close and Re-Open Mobiglass
• Replace the removed Component and Save the Build again.

The gun rack should be saved to the ship build as well now. It will Increase repair costs but may not actually replace missing guns. I have found that guns that you can purchase in-game usually come back on a repair, but any other guns that you can’t purchase in-game only come back on a claim (sub gear, web store items).

As a cheat sheet, here’s what I know so far has Gun Racks:

Do you have a GPU in there with the Stable Diffusion? If not how’s it working? I’m debating moving to a machine I can’t guarantee my spare GPU will fit in.2
