Product description Bering Optics' D-740 4x69 Premium Night Vision Riflescope is a versatile and robust night vision riflescope that offers outstanding performance. It features a 3rd generation intensifier tube with an autogated power supply and a filmless microchannel plate, which increases a signal-to-noise ratio and an efficiency of the intensifier. The autogating greatly improves sensitivity in low-light and varying lighting conditions, protects against bright light burnout, and extends life. The manual gain allows operators to have full control of the trade-off between amount of detail and image brightness.
The optical system offers high-grade multi-coated lenses that deliver bright and clear images. The 110mm f/1.6 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 provides an infrared illuminator. To help you get a precision shot, this night vision optic is equipped with a red-green mil-dot reticle with adjustable brightness.
The polymer housing is lightweight, impact-resistant, fogproof, and waterproof. 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
