"Tritium is a radioactive isotope of the element hydrogen. Tritium is radioactive and has a half-life of about 12.5 years, which means that half of the radioactive atoms will decay naturally in that time."
So based on that, id say youd be able to see it for 25 years, but the last 5 or 6 years might be really dim.
that's a good idea right there...^^^^Contact Trijicon and talk to them about replacing the vials. It usually comes out cheaper than replacing the sights, and you get fresher vials than those that may have been sitting on a store shelf for a year or more.

will they do that?
grumpier, last time I checked on it, it ended up being about $80 when you added cost + shipping, etc.
Oh, that's not bad at all.
But there's no way I'm sending my ACOG to be refilled. I'll just use it as a fiberoptic daylight only scope when the glowzy fades.
