Developed within the INFN LASA and CERN collaboration agreement for the construction of the High Order Corrector Magnets for the High Luminosity-LHC project, the first half section of the Round Coil Superferric Magnet proved the feasibility of a new compact and modular corrector magnet type using MgB$_\text{2}$ superconductor. Different from the classic superferric layout, its unconventional design exploits the iron permeability to shape, with an arbitrary number of poles, the solenoidal field created by a large bending radius coil suitable for strain-sensitive superconductors. After the design upgrade of the winding and impregnation process, in this paper, we describe the realization of the second superconducting coil for the full module length prototype of the sextupole corrector. The integration of the two half-sections of the magnet module is analyzed in detail and the performances of the newer one, during tests at cryogenic temperature, are compared with the older results. Finally, the powering test of the full module and its magnetic field characterization are described and compared with the electromagnetic simulations and expected performances.
