A readily disassemblable gun for dispensing multiple fluidic components to a mixer includes a handle having an upper barrel. A head asembly is detachably connected to a rear end of the barrel. The head assembly extends flexible, fluid transporting tubes to a forward portion of the barrel and a detachable cap is secured to the forward end for defining an initial mixing chamber between the extended ends of the tubes and a conduit extending from the cap. Fluid components to be mixed are introduced from a supply source through individual tube communicating passages in the head assembly through the tubes to the initial mixing chamber. After initial mixing, the fluidic components are dispensed into an elongate mixer for additional mixing and ultimate discharge. A trigger lever is mounted on the handle and includes a member which normally deforms the tubes for preventing flow of fluidic components therethrough and into the initial mixing chamber. The trigger lever, upon being depressed, moves the member from a tube contacting position to a nontube contacting position thereby permitting the fluidic components to be introduced to the initial mixing chamber. The head assembly, handle and barrel and the cap are all readily disassemblable so that the tubes may be quickly removed from the head assembly and cleaned or replaced. Additionally, a further tube is disposed above the fluidic transpoting tubes for selectively discharging a cleaning solvent into the mixing chamber.
