Designed for use on medium and large caliber firearms, the D-440’s extraordinary performance is the result of coupling a Mil Spec Gen 2+ image intensifier with high-resolution optics. A micro-click Side-Wheel Objective Focus and illuminated Mil Dot amber-on-green reticle ensure quick target acquisition on the darkest nights. The rugged D-440 features a shock-resistant, waterproof, aluminum alloy housing; a low-profile, high-strength, weaver mount; precision positive-click windage/elevation adjustments; and an integrated mount for an optional Long-Range IR Illuminator.
The D-440 can be easily converted without tools into a powerful, long-range 6x sight with the addition of an optional magnification doubler.
