In a traditional gearbox, the upper shell positions and aligns the HPA system with the hop-up. Because the alignment is now built into the Direct Attachment front cylinders, that portion of the gearbox is no longer needed. The electronics, and trigger\/selector system can still be housed in a modified shell, a printed lower, or a completely custom chassis.
