About David Marshall Williams
David Marshall Williams (November 13, 1900 – January 8, 1975) was an American firearms designer and convicted murderer who invented the floating chamber and the short-stroke gas piston. Both designs used the high-pressure gas generated in or near the breech of the firearm to operate the action of semi-automatic firearms like the M1 Carbine.
