The Meprolight FT Bullseye Sight (part no. 631433108) is built for the Kriss Sphinx pistol using Meprolight’s patented optical-illumination design. A fiber-optic element gathers ambient light for daylight brightness while a genuine tritium element carries the sight through the night, giving a consistent green dot in any lighting condition without batteries.

Key Specifications
