The Meprolight FT Bullseye Sight (part no. 632163108) is a fixed tritium/fiber-optic front sight built for the compact SIG SAUER P365. Meprolight’s patented optical-illumination design pairs fiber-optic gathering for daylight brightness with a true tritium element for night use, giving the P365 an illuminated green dot inside a circle Bullseye aim point without adding batteries or bulk to a slim carry gun.

Key Specifications

• Design is based on a patented optical illumination method, giving an extremely small, low-profile pistol sight.
• Works similarly to a reflex sight, presenting an illuminated dot inside a circle Bullseye aim point.
• Combines fiber-optic and tritium elements so the green dot works accurately in any lighting condition without batteries.
• Fiber-optic gathers ambient light for bright-light and daylight use.
• Tritium provides instant illumination at night or in low light.
• Installs on existing pistol dovetails and eliminates the need for a separate front sight.
