I've been running the "stock" sights that came on the rifle. It's been used on three deer hunts and scored three times, so I can't complain.
Me too. I'm not a huge fan of semi buckhorns, but the stock Marlin rear sights were pretty much dead-on and I stuck with them on the rifles not tapped on the side.
On the stock buckhorns, I flip the insert over to hide the white diamond, and I put a dab of almond appliance touch-up paint on the gold bead front sight to effect a "poor man's ivory bead." With eyes halfway to 114, I can't see gold beads in sunny conditions. Ivory beads, or white/almond painted beads are just the ticket.
