The Dead-Center Micro Shotgun Sight from LimbSaver is a universal low-profile adhesive mount sight that works with practically any shotgun. The sight's super-bright fiber optic center dot is surrounded by a color contrasting fiber optic outer ring to create a unique, dual-color rod with exceptional contrast and clarity in all light conditions. The sight's plastic base fits over a ventilated rib and is held firmly in place with a high-strength magnet or adhesive strip. Interchangeable, low profile mounting adapters fit snugly over a wide range of rib widths to eliminate lateral movement. Requires removal of original front sight. Fits ventilated rib widths: .24", .25", .29", .313", .315", and .39".
