Night vision capable at MY place includes guns that are outfitted with visible light and lasers.
Doesn't take much of a white light or laser to turn a shotgun (or any other gun) into a 25 yard rig that will work fine when you have passively found your quarry with unassisted NV be it I squared NV or thermal.
That is where my cheap lasers and many cheap, low power LED lights end up - attached however possible on old, non-railed, clunker guns that might need to hit within 6", inside of reasonable self defense distances, if necessary.
So what if the light comes on just before the shot rings out? You are going to shoot - move - shoot anyway if it is that kind of an event. We did it for decades without NV and only with white light. It's a good idea and it's easy to fold in the NV ability with the same equipment. With NV, the dimmest led flashlight or red laser often suffices.
My real night vision guns are outfitted properly (for me) with much better quality gear, but none are set up with shots beyond 100 yards in mind.
