I have a set of Mossberg Ghost Rings on my 870. They work great, especially considering the price. However, I recently saw an article in a gun rag with a VangComped 590A1. The gun had the factory sights, but had a tritium front dot sight that was dovetailed for the factory base.

I honestly dont care if its tritium or not, even fiber optic would be OK, I just want a big, hinkin, round dot for these sights. Anyone know where I can find this sight? I have searched the XS Sights website, Brownells, Trijicon, Williams, etc...Im going nuts............
