A micro dot on the Shield RMSc footprint mounts to a Picatinny rail through a Picatinny mount cut for RMSc. The Holosun K-series and the EPS Carry use this footprint.
It is not the RMR pattern. An RMSc mount will not take an RMR dot and an RMR mount will not take an RMSc dot, so buy the mount that matches the sight's footprint.
