It's been a few years now since I had an NV scope, but I used a "Corsak infrared laser". There were two models available when I bought mine - one with turrets to make it easier to zero and one's that didn't have a turret that were cheaper but not very easy to zero. (I had the cheaper one that wasn't very easy to zero).

I don't know what the NV lads use now or whether you can still buy them. Maybe someone on the NV sub forum will know.
