have this issue too
Doubleclicking on the hand guard while having it on your back puts the hand guard on your hands/inventory making it possible to then add a hand guard to the weapon again
nop this doesnt work, its not that you could even swap the attachment, you cannot even detatch it: its like a non moveable part, and when you try to drag a new attachment of same class over it the item you are dragging is getting this red - "is not fitting there" background color.
