  The Muon Accelerator Program (MAP) has completed a four-year study on the
feasibility of muon colliders and on using stored muon beams for neutrinos.
That study was broadly successful in its goals, establishing the feasibility of
heavy lepton colliders (HLCs) from the 125 GeV Higgs Factory to more than 10
TeV, as well as exploring using a {\mu} storage ring (MSR) for neutrinos, and
establishing that MSRs could provide factory-level intensities of $\nu_e
(\bar{\nu}_e)$ and $\bar{\nu}_\mu$ $({\nu}_\mu)$ beams. The key components of
the collider and neutrino factory systems were identified. Feasible designs and
detailed simulations of all of these components have been obtained, including
some initial hardware component tests, setting the stage for future
implementation where resources are available and the precise physics goals
become apparent.
