Can The Tritium in An ACOG Be Replaced?

Trijicon ACOG sights are some of the most popular and reliable optics on the market. However, like all things, they eventually need to be serviced. One of the most common maintenance tasks for ACOG sights is tritium replacement.

Tritium is a radioactive isotope of hydrogen that is used to power the illuminated reticles in ACOG sights. Tritium has a half-life of 12.3 years, so after about 12 years, the tritium in your ACOG sight will be at half of its original brightness. After about 25 years, the tritium will be so dim that it will be difficult to see.

However, you can return it anytime to Trijicon to get it replaced. So, yes, the tritium in an ACOG is replaceable. 

Can I replace the tritium in my ACOG sight myself?

I would not recommend replacing the tritium in your ACOG sight yourself. ACOG sights are sealed with nitrogen gas to prevent internal condensation on the lenses. To replace the tritium, the ACOG sight must be disassembled, the tritium capsules replaced, and the nitrogen gas replenished. This requires specialized tools and equipment that are not typically available to the average person.
