Frequently Asked Questions
Will these night sights fit my AR-15 if it's not a Colt-branded rifle?
This set is specifically designed to fit Colt M16 and AR-15 pattern rifles using standard Colt-spec front and rear sight dimensions. Many AR-15 variants share compatible sight dimensions, but fitment can vary by manufacturer. If you're unsure whether your rifle uses Colt-compatible sight specs, consult your firearm's manual or contact Trijicon directly before purchasing to confirm compatibility.
Do tritium night sights require batteries or any power source?
No — Trijicon tritium sights are entirely self-luminous and require no batteries, electronics, or external light source to activate. The tritium gas capsules glow continuously through a natural process called radioluminescence, providing a reliable sight picture in total darkness without any user action required. The tritium lamps have an approximate service life of 12 years before the glow begins to dim noticeably.
How do these sights perform in bright daylight compared to standard iron sights?
Trijicon engineered this 3-dot set with enhanced daylight dot visibility, meaning the tritium lamps and surrounding sight design are optimized to maintain a clear, high-contrast aiming reference even in full sunlight — a common challenge with some night sight designs. You get the best of both worlds: a crisp daytime sight picture and automatic low-light illumination without needing to adjust or switch anything.
