Marble's Expert Shotgun Front Bead Sight .094" Diameter 3-56 and M2.5x0.45 Thread 3/32" Shank Fiber Optic
Material: Steel bead body
Gunsmithing Required: Yes
Notes: The Fiber Optic bead is bright enough to see clearly but unobtrusive
enough to not alter the traditional look of your shotgun. A great companion
with Marble's Fiber Optic Universal Rear Sight.
