Available in either high performance Gen 2+ or Cutting Edge Gen 3 US technology, the D-740 is the ultimate in night vision weapon sight development. With a 4x, 100mm f1.5 multi-coated, high-grade lens system; dual-color, variable-brightness, illuminated Mil Dot reticle; top mounted objective focus; and easy-to-use micro-click windage & elevation target turrets, the D-740 makes precise target acquisition possible even in extremely low-light conditions. The waterproof, nitrogen purged housing is made from advanced materials which reduce weight and improve recoil resistance. The low profile, heavy-duty Weaver mounting system guarantees zero retention on heavy caliber weapons (including .50 BMG class). The D-740 is the premier choice when precise target acquisition is essential.
