Product description Bering Optics' D-740 4x67 High-Performance Night Vision Riflescope is a versatile and robust night vision riflescope that offers outstanding performance. It features a 2nd generation intensifier tube that offers a great advantage over the first generation tubes by providing greater sensitivity and higher gain. The gain control of this tube type is manual one, which allows an operator to have a full control of the trade-off between amount of detail and image brightness. The tube is also enhanced with the white phosphor technology for operators who prefer black and white images to green ones.
The optical system offers high-grade multi-coated lenses that deliver bright and clear images. The 100 mm f/1.5 objective lens offers a wide aperture for collecting more light at night and enhancing visibility. To enable operation in nearly-complete darkness, providing additional illumination for your targets, this night vision device offers an infrared illuminator. To help you get a precise shot, this night vision optic is equipped with a red-on-white mil-dot reticle with adjustable brightness.
The polymer housing is lightweight, impact-resistant, and water-resistant. For attachment to your firearm, this device provides a Weaver-style mount. Also included is a carrying pouch with a strap, a protective lens cap, and two AA batteries. - Image Intensifier
