info on Hardcore run-n-gunner

Does anybody have any info on these layouts? I have a chance to buy some pretty cheap.
They look to be nice and simple design which will help us where we're hunting at, but I just wanted to see if anybody has used one or knows anything about them before I order them.
Thanks

That is what I use. Simple and quick to set-up in the dark. Easy to move if the birds change their pattern. Very handy that it doubles as decoy bag. I have used the standard style lay-out for years, and needed to replace it. I had a buddy that use these,so I borrowed it while Uncle Sam had him in a duckless region on Earth. I liked it and knew I would buy this when time came to replace my old one.
