Meprolight Sights Ml63143 Fiber-Tritium Bullseye Green Sight For Kriss Sphinx
$139.99
The Meprolight Sights ML63143 is a fiber-tritium bullseye sight designed specifically for the Kriss Vector and Sphinx platforms. This compact optical pistol sight delivers what matters most in a carry or duty optic: fast target acquisition without electronics, batteries, or maintenance. The dual-illumination system pairs fiber optic elements for bright-light performance with premium-grade tritium for reliable low-light and nighttime shooting, giving you consistent aim point visibility across any tactical or hunting scenario.
The Meprolight FT Bullseye uses a patented optical design to project an illuminated dot surrounded by a circular reticle—think of it as a reflex sight without the red dot's dependency on power. In daylight, the fiber optic collects ambient light; in darkness or heavy cover, tritium takes over. There's no learning curve, no battery check before you leave, and no on/off switches to fumble. It's always ready the moment you draw.
Installation is straightforward: the sight mounts to your Kriss Sphinx's existing dovetail, eliminating the need for a front sight and keeping your profile low enough to work with most standard holsters. That compact footprint—smaller than most reflex sights—means faster draw and less snag on gear. The tritium element is warranted for 12 years of nighttime visibility, so you're looking at genuine longevity in an EDC or duty context.

Frequently Asked Questions
Will this sight work on my Kriss Sphinx without modification?
Yes. The ML63143 is engineered specifically for Kriss Sphinx pistols and mounts directly to the existing dovetail. Because it replaces the front sight, no additional gunsmithing is needed.
How does a fiber-tritium sight work without batteries?
The sight uses two passive illumination sources: fiber optic elements that collect and transmit ambient light for daylight shooting, and tritium gas vials that glow continuously in darkness or low light. There's no LED, no electronics, and nothing to charge—it's always on and always ready.
Will this sight work with my current holster?
The Meprolight FT Bullseye is designed as a low-profile optical sight that fits most existing holsters, since it eliminates the front sight entirely. However, holster fit can vary by manufacturer and design; if you have concerns, verify with your holster maker or contact us.
How long does the tritium glow last?
Meprolight guarantees nighttime illumination for 12 years from the date of manufacture. After that period, the tritium gradually fades, though some low-level glow may persist for years beyond the warranty.
