Maxim received a patent in 1891 for a short-stroke gas piston, where the gas is taken off through a barrel port close to the chamber, which drives a short piston that operates the action. John Browning, in 1889, entered the SR field, producing a lever rifle that featured a concave muzzle cap that was hook up below the barrel, connecting with the triggerguard rifle lever.
