VLTOR MUR Upper with Daniel Defense RIS-II?

[TehLlama]

Would I have a problem installing a Mk18 RIS-II onto a MUR-1A upper?

Of course, an installed picture would be invaluable

I've seen Stickman post pictures of a MUR-1S with a DD Lite 12" rail. The Lite and RIS II have a similar lock up device so I think it should work. Might be best to ask DD or Vltor directly. Vltor has sent me same day emails on technical support questions.
