I guess my googlefu is not working today but I cannot come across a set of new sights for my new Rem. 870. Right now it only has a bead front sight but I would like a set of ghost rings sights with maybe trijicon or something of that sort. Any help will be appreciated. It came with the two shot extension that is one less thing I need. But also it says it is a seven shot but when I load into the tube I only can get six. Does it mean six in the tube on in the chamber or what. Also someone suggest some HD shells. I has been a while since I have owned a shotty.
