Williams Fire Sight - peep sight replacement

[Andy1]

I've been looking for a replacement for the Wiiliams fire sights on my Ruger Single Ten. I've debated on getting a factory V blade and base or forking over $100 for a Bowen sight.

I've already replaced the front sight with a Marble Arms dovetail ramp and a 1/16" white pin that I read about on a Chuck Hawks article. I had to grind down a #6-40 flathead screw from Fastenal.

Today I happened across this Eagle Eye Peep Sight from Tandem Kross. It's a straight drop in replacement to the Williams base. I've never heard of it and couldn't find a thread about it I here. But they're $20 so I ordered one when I got home from work.

Has anyone seen this or know anything about it?

*Update*

For anyone interested in this peep sight. I contacted Tandem Kross and found out the aperture opening is .235". There is no mention of this in the product's description.

**Update #2**

I received and installed the new peep sight. Photos included.

1, it works just as I hoped, but...
2, I had to remove the Marble Arms front sight I just installed because when viewed at arm's length thru the peep, the white pin gets blurred black and you can't focus your sight picture.
3, you can see I had to reinstall the Williams fiber optic front pin so I could see my sight picture correctly.

I hope this information helps anyone else and saves you the time and money I spent figuring it out.
