Great in low light, Dead Ringer's Duck Buster sight provides you with quick target acquisition thanks to its oval design molded from optical Lexan with large compass points. If the bird's wings are horizontally touching both the right and left compass points, you can feel confident it's within 30 to 35 yards from you – the optimal kill zone of most shotguns. Adjustable for windage and elevation, it fits 1/4", 5/16" and 3/8" ribbed guns and doesn't require tape. The low-profile mounting system and small-diameter optical device is designed to perform in any weather and have superior brightness. Easy to mount. Imported. Color/camo pattern: Black, Mossy Oak® Duck Blind®.
