The KonuShot 3X-9X32 is affordable and dependable, as its metal construction was designed to withstand the most extreme environments. Even altitude changes will not cause your KonuShot to fog, leak, or lose alignment. The KonuShot has coated optics, providing great luminosity, and a wide field of view. The 3X-9X32 offers a full range of zoom magnifications with a low profile objective lens that is perfect for use on all smal bore guns. As with all Konus scopes, they are nitrogen purged for true waterproof & fogproof integrity, as well as being shockproof.
