HiViz Sight for Mark I?

[Black Fly]

I have recently become enamored with fibre optic sights. It all started with a Browning double rifle. I could suddenly see the front sight. clearly. It had been a long time. My open sight shooting has greatly improved. My new SP 4" kit gun drove the point home. I am thinking about adding one to my old Mark I. I have tried paint, but just not as good. Does the HiViz sight number HRB2007, which fits the Mk II and Mk III heavy barrels, fit the Mk I Target as well?
Thanks
