Dead Ringer's Drop Box sight is a front- and rear-sight system that provides quick target acquisition, especially for cross-eye dominant shooters who shoot with the hand opposite of the eye they're aiming with. The Drop Box sight allows both eyes to stay open while tracking aerial targets through the rectangular design with its six large compass points. Made of aircraft-grade 6061 T-6 aluminum, the sights have hardened-steel screws with threaded steel plates for attachment. 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 with the included, patent-pending twist-lock key. Imported. Color/camo pattern: Black, Mossy Oak® Duck Blind®.
