Fiber Optic and Tritium Together

Combining bright fiber optic tubes with self-illuminating tritium gives you flexibility across variable lighting. The fiber optic front sight gathers ambient light for daytime brightness, while tritium handles dusk and dark environments without battery dependence. This redundancy means your sight picture stays sharp whether you're at the range in afternoon sun or training after hours. Check our California gun-buyer FAQ for details on sight installation and zeroing procedures. Visit our firearms dealer in Sunnyvale for our full catalog.

Frequently asked questions

Will these sights co-witness below my slide-mounted optic?

Yes. Night Fision engineered these at optic height specifically so front and rear dots sit at the same plane as RMR, 507C, SRO, and ACRO footprints. You'll maintain a usable sight picture if your optic fails.

How long does the tritium stay bright?

Tritium has a half-life of approximately 12 years, meaning brightness gradually decreases but remains visible for decades. Most shooters replace sights for performance upgrades long before tritium dims significantly.

What do I need to bring for DROS in California?

Bring a valid California driver's license or ID card, proof of residency, your Firearm Safety Certificate (FSC), and payment for the firearm and transfer fees. Looking for gun store Cupertino? Visit us in Sunnyvale.
