A manual extruder for accurately and precisely extruding composite resin type material which includes an elongated tubular barrel having a readily detachable nozzle tip and an associated plunger for extruding the material to be dispensed from the nozzle tip. A pistol grip shaped handle is connected to the barrel and to which there is pivotally connected an actuating lever bearing on the plunger whereby the lever can be squeezed relative to the handle to provide the necessary mechanical advantage on the plunger for extruding the material with the use of one hand.
