I'm strangely intrigued by this. Looks like something I could stash under the spare tire in my vehicle for SHTF scenarios (or just have a 16" barrel rifle that fits in a backpack or whatever...)

Anyway, does anyone here have any real world experience with this? The Air Force adopted it for their pilot survival rifle, so I assume it's been tested, but we all know about assuming things.
