.475 A&M Magnum
It's a cool idea and a viable option for anyone that lives in a state that isn't chasing it's own tail off a cliff. I would definitely consider one if I lived in America. I also want very badly to build a 9mm/40 AR lower and upper that accepts Glock mags. I really like the AR platform and now that I have a Glock, would love one in pistol caliber.
