Has anyone ever used these peep sights? I'm thinking about buying one for my guide gun but was looking for some input. $54 dollars for a adjustable apeture sight seems very reasonable.

They are a great bargain!
I put a set on my Marlin 1894CB and could not be happier.

I have to agree with Salvo! I took a Marbles Tang off my 1894CP to put on a LowPro and love it.

Ditto here. Put a set on my 1894C to replace some XS sights that looked out of place. The Skinners are high quality and look right on a lever gun.

Thanks for the input. Do I need to replace the front post as well? It looks like the factory one is too short. Also, this will be my first set of aparture sights, what size aparture should I get?

I'm watching this one carefully as I also have an 1894 that needs Peep/Ghost rings. I have been looking at Skinner.

Put a set on two of my 1894's. I should have done this long ago. Definitely a quality product.

+1 on the skinner sights and if you to go the web site, you will find the calculations to determine the height of the front site.
