  We present the results of a multi-epoch and multi-instrument study of the
supermassive black hole at the center of the galaxy MCG-05-23-16 aiming at the
determination of its spin. We have analyzed high quality X-ray data of
MCG-05-23-16 from XMM-Newton, Suzaku, and NuSTAR obtained over a period of
about 10~years. We have built a double-reflection spectral model that well
describes the observed spectrum based on prior results suggesting that the iron
K$\alpha$ line includes both a broad component from the disk's reflection
spectrum and a narrow component due to fluorescence and scattering off material
by more distant matter. Our measurement of the black hole spin parameter is
$a_* = 0.856\pm0.006$ (99\% confidence level).
