I put a Hi-Viz 'snap on' bead on my 20 gauge Pardner. If you have not seen them they are made out of a tough black plastic and they snap over the barrel of plain shotgun barrels (no ventilated rib types) up against the factory bead. Worked pretty good! I can pick out the bead with NO problem now. Kinda pricey however at $25. Mine came with a few different bead colors. They fit tight and don't budge at all, even after many shots. Sits a little higher than the factory bead though. Worked well for me. I'd just thought I'd pass it along. :grin:
