Like the title says, I found new tritium for my M70 (thanks Paintwerk!!), but need to pull the old vials. I have an appropriate sized drill bit, but wanted to see if there was a better way to do it than the old smash and pick.

Once I got them out, silicone to hold the new ones in? Until I cleaned the crud off, I didnt even know that the front one still glowed (but very, very faintly).
