a syringe comprising a distal neck portion, a needle attached to the distal neck portion, a barrel defining a cavity for a medicament, and a proximal finger flange, the barrel extending from the distal neck portion to the proximal finger flange;

a needle shield removably attached to the syringe to cover the needle; and

a syringe carrier having a sidewall defining a c-shape with a longitudinal slot extending along an entire axial length of the syringe carrier, the sidewall configured to snap over the barrel of the syringe when the syringe is inserted into the syringe carrier in a direction perpendicular to a longitudinal axis of the syringe carrier,

wherein the syringe carrier comprises an inward protrusion extending inward from a distal end of the sidewall and configured to engage the distal neck portion of the syringe to limit distal movement of the syringe relative to the syringe carrier when the syringe is disposed in the syringe carrier,

wherein the syringe carrier comprises two elements extending outward and proximally from a proximal end of the sidewall and defining a recess to receive the proximal finger flange of the syringe when the syringe is disposed in the syringe carrier,

wherein each element of the two elements has a distal wall and a proximal wall, the proximal wall configured to limit proximal movement of the proximal finger flange relative to the syringe carrier when the syringe is disposed in the syringe carrier, and

wherein the syringe carrier and the syringe are configured such that when the syringe is disposed in the syringe carrier with the distal neck portion of the syringe contacting the inward protrusion, a distal side of the proximal finger flange is proximally spaced from a proximal side of the distal walls of the two elements.
