Scoped Assault Rifle

I’m interested in making a mod that allows players to put scopes on assault rifles, and I was wondering how to go about that. I’m in PrimalEarth/CoreBlueprints/WeapRifle. I see the WeapRifle versions for all the other attachments, so I assume I have to make one for the Scoped, but I’m not sure where to configure it within the WeapRifle for it to be able to take the attachment, if that’s what I have to do at all.

Also, I assume I’ll have to make/modify a mesh to show the Scope on the Rifle in game. Just need some guidance on where to start.

Edit:
I thought to check the Attachment instead of the Weapon File. Under PrimalEarth/Items/WeaponAttachments. I found the scope and it has a parameter for Support Drag Onto Item Classes to setup being able to put the attachment on the weapon. Then there is a parameter for Support Drag Onto Weapon Item Weapon Templates, which I believe determines what is displayed on your HUD when a particular attachment is placed on the weapon. All I need now is how to modify the weapon’s template/skeleton/mesh or whatever is necessary to show the attachment on the weapon.
