Unique, universal shotgun sight bead that stays visible in all light conditions: bright sun, heavy overcast, late afternoon shadows, deep woods hunting.
Tritium gas light source sealed in the center of a blued steel bead. On bright days, the shooter sees a black bead with a light center.
As the light fades, the center becomes a soft green glow. No switches, batteries, wires, or charging. TRU-DOT bead is warranted by factory to provide usable illumination for 12 years.
