The Accufire IR300 Infrared Illuminator is the perfect accessory for your infrared scope. The IR300 comes standard with the Noctis TR1 and Noctis V1. If you have struggled with using infrared optics on nights with little to no illumination, the IR300 is designed to help with that problem. The IR300 is constructed of 6061 aluminum alloy and rated water resistant to IPX6 tandards, which means that its good to go for everything short of total submersion. It has three output settings (low, medium, high) and runs on either: one 18650 battery, or two CR123a batteries. The IR300 will run for 110 hours on the low setting, or 3 hours on the high setting. With a maximum effective range of 300 yards, the IR300 is the answer to your IR illumination needs.
