Did the MKI 678 target all have the A20-T rear sight or did they switch to the MKII style at some point? I'm looking at a 13 series gun that has a MKII style rear sight which I question as original.

I believe the rear sight on the Mark I and Mark II are identical.
But when you get to the non prefix guns Ruger used a MICRO marked steel rear sight that had a smaller profile.

Thanks Chet, that's the answer I needed. I've seen them both ways and wasn't sure which was right.
