I've tried all of those! I had a Armson OEG, which i could never get zeroed, on a FAL , a Weaver Quik Point on a Rem. 870, and an Aimpoint Mk Ii with the 3x attachment.

The light is exiting the window in parallel rays. How is it that it doesn't fill the pupil (about 2.5mm diameter) or the NVG lense? It stands to reason that a 20mm square (like an ACRO) projecting collimated light from all points on the lense would be a 20mm red square going backwards in space.

I got to shoot a shotgun with an OEG at thrown clay pigeons a few years ago. An odd setup but it did kind of work.
