In SureFire Field Notes 74, Jamey Caldwell of 1 Minute Out discusses how to properly set up a carbine for both day and night use with NVGs. You can click and view the video above.

Caldwell has developed a specific setup to make his carbine more efficient and more fluid when operating in dark environments whether he is operating with NVGs or not. This setup allows Caldwell to go from IR to white light at any given time. Caldwell notes that most NVGs drastically reduce the field of view from the human eye’s natural 200 degrees to just 40 degrees. The limitation can increase the hazards of clearing small rooms quickly. He often chooses to splash white light with his  Scout Light® and look under the NVGs (Caldwell doesn’t run eyecups).

But carbine setup is critical. Caldwell prefers to adjust the brightness of his optic so that he can see the dot in the daytime or when using white light in a dark space. However, he balances the brightness to leave the dot dim enough that he can look through the optic and engage threats in low light without whiting out the NVGs. Caldwell favors the compact SureFire M300V Scout Light® on his carbine because it provides both white light and IR capability. However, he generally sets it to white light mode and uses an IR laser that’s set to activate flood illumination and the laser simultaneously when he uses NVGs. Caldwell says that this setup helps him to be fast efficient and fluid when faced with a low-light environment where threats may be present.
