Lets take for example a gun with an internal (default inseperable) scope 2x. We define a transformation that changes from 2x to 4x. When we change the scope, this is what happens nominally:

A) The 2x Scope is erased, because it's one of the gun's default inseperable attachments.
B) Any other attachments are copied to memory.
C) All attachments are erased from the gun.
D) A new 2x Scope is attached to the gun, because it's one of the gun's default inseperable attachments.
E) All other attachments in memory are reattached.
