If you've got nothing to do and want to give your airsoft gun a sci-fi look especially in the dark, watch this Howto from Lord Draconical showing you how he does it for Nerf Guns and should also work for AEGs. It may not be tactical-looking but it will look great in the dark.. "Putting custom lightwork into Nerf guns is something I am well known for, so I thought it was time to make a video explaining my process for how I do it, so that you can do the same!"
