I have an H&R Pardner 12 gauge that I keep around for home defense. The shotgun came with a bead sight, which was fine, but I simply wanted a bit more. I ordered a Hi-Viz fiber optic sight which really helped. I have it set as the green tube, and it simply picks up ambient light and just looks like its glowing and makes it easy to aim. It's a very cheap (less than $20) option.
