Wilson rear sights suitable for bullseye use on a 1911?

The title pretty much asks the question.
I'm building a new pistol and it looks like the Wilson sight is quite nice and will be a relatively simple install.
Is anyone here using one or have any experience with them?

Thanks in advance.

there are lots of different Wilson sights.  Can you post a link for the one you are talking about?

I like the low mount but don't like having to machine the notch in the back of the slide for it to fit.

any sight like that will do great in bullseye.
