I was wondering if i could put tru glo sights on my nova. I like the rear ones and was wondering if that was possible, and if i cant use the tru glo is there any kind of rear sights i can put on it

Do you have a slug barrel on it? It's the only barrel for it that doesn't have a vent rib. If not, Tru-Glo and a few others make rear fiber optic sights that clamp onto the vent rib. Try your local Wal-Mart, or other sporting goods store.
