Brix Tactical shows how to do this in this video. This 4-in-1 device, housed in an anodized aluminum body, integrates a green laser, an IR laser, an IR illuminator with variable beam divergence (~17 MRAD to ~120 MRAD), and a 1000-lumen white light (80,000 Candela). It features slave lasers (no separate calibration required) for both visible and IR, suitable for 7.62x51 recoil. A factory default low-power safety mode is included, with an option to activate high-power mode.
