Hello jimmymo!
Wecome to the forum. There are lots of great folks hear who know a great deal about the Handi's. You found the correct location to learn about the Handi Rifles, but it does get addictive.
I don't know very much about the gray laminated wood, but have picked up some info along the way.
From what I've learned they don't appear to be a regular production item. I've only seen two of them in gun shops and each was being sold as a package with a scope, rings and mounts. I have seen this twice. Once in a shop in PA and in a shop in Harrisonburg, Va. These are the only two places I've seen the gray laminates on a shelf. The employee at the Va shop said they are available as a special order to dealers and come as a scoped package deal. His version had a Bushnell Banner, I believe.
I purchased the one in Pa. It was a 7mm-08 and came with a Bushnell Sportsman 3X9.
In a conversation with a gentleman at NEF customer service a while back, I learned that the Gray Laminate wood is available for purchase. There is a part number, but I don't recall what it was.
Now that a think about it, I seem to recall that the gentleman told me that the Gray's were available to dealers upon request, but I cannot recall if he said they were exclusive to a scoped package deal.
Hope this helps. If you should find out anything further, lets us know.
Again, welcome.
