I have a Remington 870 Express that I took out shooting for it's 2nd time a few days ago. During the outing, somehow the little brass ball managed to escape from the vent rib. I'm not sure what I should do. I assume the brass ball was simply pressed in, as the hole does not appear to be threaded. I think I would like to have some sort of sight on it as I plan to go pheasant hunting with my brother after he returns from Iraq. On that note, I've never been hunting. I've seen some cheap fiber optic sights that attach to the vent rib- should I get some of these? (I'm guessing not as they will likely fall off even easier) Should I find a small tap, thread the hole from the old pin, and make a replacement? Or would I even need to fix it? A majority of it's life will be spent hanging behind my headboard in case shtf. I prefer not to replace the barrel as I've checked some prices, and a 26" $175 barrel was too much for my gun I paid $180 for.
