The DRS-NV (Digital Rifle Sight-Night Vision) is a red dot and digital night vision fusion sight that combines Holosuns red dot sight technology with digital night vision capability. DRS-NV features an LED MRS (Multi-Reticle System) with three digital reticle options, 1024×768 resolution digital night vision sensor with up to 60fps, 8x digital zoom, digital image and video recording with on-board storage. The DRS is powered by two 18350 rechargeable flat-top batteries with 6 hour run time in full function mode and 8 hours of run time in observation mode. An onboard magnetic coupler connects DRS to USB power for charging the batteries or to a PC for downloading of recorded images and video. DRS-NV units amplify light to improve low light visibility. Moonlight and starlight provide sufficient lighting in most cases, however, during periods where cloud cover blocks moonlight and starlight, an external infrared (IR) illumination source is needed. Holosun recommends one of our laser devices with IR Illumination such as the LE321, or LS321. Verify your local and/or state laws before attaching and IR illumination device to a firearm with a night vision device. IP67 Waterproof.
