Meprolight Sights Ml63214 Fiber-Tritium Bullseye Green Front Sight For Sig Sauer P320
$129.99
The Meprolight Sights ML63214 Fiber-Tritium Bullseye is a compact, battery-free front sight for the Sig Sauer P320 that combines fiber-optic and tritium illumination into a single, low-profile optical aiming system. Unlike traditional two-dot sight pictures, this sight presents a familiar bullseye pattern—an illuminated dot centered in a circle—that many shooters find more intuitive for fast, accurate target acquisition. Whether you're training under bright daylight or responding in darkness, you get instant sight picture without fumbling for batteries, switches, or complicated electronics.
The dual-illumination design is the real difference-maker here. During daylight or bright conditions, the fiber-optic element gathers ambient light and delivers a vivid sight picture. When the sun sets or you move indoors, tritium takes over, providing self-illuminated aiming reference guaranteed for 12 years with zero battery drain. There's no switching, no adjustment—just always-ready visibility in any lighting scenario you're likely to encounter at the range, in your home, or in the field.
Installation is straightforward: the sight mounts to your P320's existing front sight dovetail, and because of its small optical footprint, it clears most standard holsters without modification. You don't need to remove or replace your existing front sight setup, making this an easy upgrade path for shooters who want a faster sight picture without a complete sight system overhaul.

Frequently Asked Questions
Is this sight compatible with my Sig Sauer P320?
Yes, the ML63214 mounts directly to the P320's front sight dovetail and is designed specifically for this platform.
Do I need batteries or a power source to use this sight?
No. The Meprolight Fiber-Tritium Bullseye is completely battery-free. Fiber optics gather ambient light during the day, and tritium self-illuminates at night and in low light—no switches, charging, or maintenance required.
Will this sight work with my existing holster?
The sight's low-profile optical design is compatible with most standard P320 holsters, though holster fit can vary by model. It's worth checking with your holster manufacturer if you have concerns.
How long does the tritium illumination last?
Meprolight guarantees tritium illumination for 12 years from the date of manufacture. After that period, the tritium will gradually dim, but the fiber-optic element will continue to function in daylight conditions.
