A plunger sub-assembly () for a pre-filled medicament injector for expelling a dose of a medicament, comprising: a) a container () holding a medicament, the container () comprising a body () with a proximally facing rim surface (), and a distally slideable piston (); b) a plunger (); and c) a tolerance compensating element () configured to cooperate with the plunger () and to cooperate with either the proximally facing rim surface () or the piston (), the tolerance compensating element () being rotatable relative to the plunger () to adjust the piston () end of dose position. The plunger sub-assembly () is formed so that end of dose state occurs by the plunger () cooperating with the proximally facing rim surface (). Pre-filled medicament injectors and methods of assembling a pre-filled medicament injector are further described.
