We shoot in a big gravel pit far (miles) from any houses, businesses, etc. During daylight savings time we run night HG once a month, with HG/rifle twice, and HG/SG once during those months.
We have used flashlights, ambient light, (on a full moon, you would be surprised how well you can see) weapon mounted lights, headlights, flashing lights, even strobe fireworks thrown out in front of the shooter just before the buzzer. I set up a HG stage with four spot lights shining in the shooter's face, run by a generator off in the woods. The targets were behind the wall the lights were mounted on. When the shooter flipped off the switch for the lights, it went dark, and the buzzer was hit. (the RO faced him until that point to make sure he didn't close his eyes to get accustomed to the dark) He then had to engage his targets in the dark. This was to simulate running into a dark building from out in the bright sunshine. Just a hint, good night sights are your friend in the dark.
We do dark rifle at close up out to 90 yds. On some targets we mount a flashing red LED on the targets rt. shoulder to show "muzzle blast" and the shooter has to figure over and down from there to get his hits. Some times folks fixate on the LEDs, so keep some spares. ETA: Also, rifle steel at around 60-70 yds with some type of low lighting on them (I use a lantern a few yds away) is lots of fun, esp. when hit with mild steel jacket ammo such as wolf. Can you say SPARKS?!!)
Iron sights on rifles work OK if you have ambient light to see them. Optics work well, esp. if you have some light to see your reticule. Dots work best, but you need one that can be turned WAY down. Many will "bleed" into the entire screen even on the lowest setting, so you need to play with them to see which work best.
This can only be done in a remote place that has secured access. It is also done with high walls, and the shooter is watched very carefully, by ALL on hand, not just the RO. Extreme care must be used. This is for information purpose only, to tell folks what we do, and not meant to encourage anyone else to do so.
Good luck.
