You can use a set of small locking pliers, beware that you'll probably bugger that brass bead up pretty bad getting it off though. That is if you ever had any intentions toward switching back.

To my knowledge they have been using the 5-40 thread pattern for quite some time. Much longer than 14 years I believe. I have a Mossberg 835 pushing 20 years old and it's 5-40 threaded if that tells you anything.

Another option in tritium beads is the Marbles unit:

It's a few dollars more but you get a white outline around the tritium insert. That will help some with daylight use.

I have the Marbles unit on an 870 and a 500 and have been happy with it on both. I will say that you may have to file off a bit of the shank once you get it installed. It was too long on mine and protruded into the barrel. Easy to remedy with a small half round file.

I have no direct experience with the Meprolight bead, but I have used Meprolight night sights on several handguns and have been pleased.

Take care,
Tom
