I have a GI bipod. Thirty-five, forty years ago, it was excess inventory in some supply room somewhere and needed to be gone before an inspection. It was saved from the dumpster. I'll have to see if there is a CAGE code on it somewhere. As others have mentioned it is substantial, well-made and useless. When I was issued an M14, I never saw a bipod outside the picture in the field manual. That's likely why when they were eventually surplussed they mostly looked unused.
