The RetroArms Centering Screw is a specialized component designed for use with RetroArms QSC (Quick Spring Change) spring guides. This precision-made screw helps perfectly align the spring guide inside the gearbox shell, ensuring smooth spring compression, stable performance, and reduced internal wear — especially in high-stress and high-RPS AEG builds.
CNC-machined from high-strength steel, this centering screw is a small but essential piece for techs building or maintaining RetroArms gearboxes using the QSC system.
