I'll be the contrarian ... surprised? I bet not.
I didn't like the setup on the Marlin 1894CSBL I had for a short while. The white line up the front blade doesn't work for my eyes, the front sight disappears under some light conditions. A plain black post is more visible and more precise ... for me. I'm not a fan of their ghost ring, either.
YMMV, of course. Everyone's eyes are a little different. For me ... I wouldn't do it again. (I came to the same conclusion after putting a Skinner peep on a High Wall for a while.)
