They don't "have to be placed on the end;" rather, whenever you place one, you can't attach anything to it, so that "becomes" the end of that chain at that tier level.

Depending on how high your Blood Bullet level is for Assault, you can unlock BB mutation chips that vastly increase damage at long enough range (Increased Accel) and triplicate the attached module (Triple Replication). Use these in conjunction with regular Shot-type modules to create low-cost, multi-hit and high-damage bullets (for example, a shot with triple replication and a bomb attached to the shot), and attach triple replication to the non-elemental 0-OP starting module (making that your entire bullet) for some serious OP recovery.
