Mike, I saw the cores on the Night Vision UK forum. If you need any help finding them let me know. I think he had 640 and 320 cores.
Guys, I'll let Mike post his video and pics, but he built his own NV scope and IMO it's better than the one I don't mention anymore. LOL. It doesn't autodim, and I know of several kill video's that he has posted on another forum using it.
