Of the two options I would go with the Midwest piece. Please note however that most bipods (such as the Harris) mount off of a sling swivel stud, not a Picatinny or Weaver rail as provided by the two short sections of rail you selected. There are adapters that offer a quick-release option for attaching/detaching a Harris bipod to a Picatinny rail, such as the LaRue. Probably about $80 for the adapter.
