A two-component dispensing gun has two longitudinally-extending dispensing passages receiving metering rods and in fluid communication with two feed passages adjacent to an especially configured metering rod tip and valve seats formed at the exit end of each dispensing passage. Valve seats of the dispensing passage extend as protrusions from the gun nose and are sealingly received within cup shaped recesses formed in a detachable, throwaway nozzle having a static mixing chamber. The nozzle has a truncated cone configuration which, in combination with the geometric configuration of the dispensing and feed passages alleviates turbulent flow of the liquid components until reaching the static mixer within the nozzle. A cammed surface on each metering rod in combination with a yoke crossbar formed as part of the gun's trigger provides increased motion of the trigger for fine or slow metering applications of the gun.
