Hesco/Meprolight makes a replacement tritium bead. I have installed a few of them, and so far, so good. The only thing is that when replacing the Remington bead you will need to drill and tap a slightly larger hole for the replacement sight. This is not a big deal. A gunsmith can do it cheaply, or you can buy the correct numbered drill bit and tap from Brownells, and do the job yourself.
