Not really; this may be the closest. There's a couple interesting analyses on YouTube from Forgotten Weapons of both the Gyrojet pistol and the rifle, and a couple fire tests as well. (they're from the 60s and shoot rockets, so good luck with ammo availability)

They're pretty neat, though impractical as it turns out.
