This US JSSAP prototype is intended to significantly reduce the weight associated with small arms and their ammunition. Using a High Ignition Temperature Propellant, this prototype light machine gun features belt fed caseless ammunition. Should the program be successful, this weapon system could become a great improvement over the heavier and more cumbersome squad automatic weapons currently in use.
