The Lyman Uni-Dot is a fiber optic sight that gathers available light and appears to the shooter as a brightly glowing dot in a tube only when the shotgun properly mounted. The sight can only be seen when the shooter's eye is in the correct position. This encourages shooting with both eyes open and eliminates pointing errors like lifting or dominant eye crossover.
This model features a Riblock snap on mounting that fits shotguns with 0.5" wide vent ribs. The 2mm fiber optics tubes are interchangeable, both green and red are supplied.
