1. A method for assembling an injection device comprising:
inserting a fluid container having a fluid reservoir including one of a plurality of volumes of medicament into a housing, the fluid container including an injection conduit fluidly coupled to the fluid reservoir configured to define a fluid pathway from the fluid reservoir to a patient;
setting a volume setting mechanism based on a size of the one of the plurality of volumes of medicament;
coupling the volume setting mechanism to a firing mechanism; and
coupling the firing mechanism to the fluid reservoir, the firing mechanism configured to expel one of the plurality of volumes of medicament from the fluid reservoir through the injection conduit, the firing mechanism being coupled to a dose setting mechanism configured to select all or a fraction of the one of the plurality of volumes of medicament that is injected from the injection conduit when the firing mechanism is actuated,
wherein the firing mechanism includes a ram and the volume setting mechanism includes a nut threadably coupled to the ram, the nut being releasably retained in an initial position by a latch, and
wherein setting the volume setting mechanism includes adjusting the initial position of the nut relative to the latch.
