Has anyone heard of the Air Ops AR Chassis for airforce guns? It looks like an amazing product, that let's you mount a buffer tube and standard AR stock. But the only shred of evidence they exist is 2 videos on a YouTube channel and an email that doesn't answer. I've seen the name David Dowdy somewhere, but can't find the guy. I am absolutely salivating over this thing, any knowledge of, or anyone selling this part, I'd love to hear. I just don't know where to look anymore and I'm too dumb to give up.
