There are several issues arising with the new rendition of NVGs. I've made a decent attempt at capturing the majority of these issues in the video for which I will provide a link.

1.) NVGs are turned off when you ADS with a pistol.

2.) NVGs are turned off when you return to a normal standing position from ADS position with a two handed fire arm with no scope on it.

3.) NVGs do not automatically turn on after attempting to look through a scoped weapon.

Please watch the video to see what I am talking about.
