Bones. I’m curious. I have a 686 SSR and want to install a fiber optic front sight. You say they can be replaced w/out tools. How? Mine seems to be behind a pin in the barrel.

This. I needed to grip it with pliers at least in part because the factory sight was bent to the left. Sights designated "Classic" or "DX" work. Several videos out there on YT.
