  We report TeV gamma-ray observations of the ultra-high-energy source MGRO
J1908+06 using data from the High Altitude Water Cherenkov (HAWC) Observatory.
This source is one of the highest-energy known gamma-ray sources, with emission
extending past 200 TeV. Modeling suggests that the bulk of the TeV gamma-ray
emission is leptonic in nature, driven by the energetic radio-faint pulsar PSR
J1907+0602. Depending on what assumptions are included in the model, a hadronic
component may also be allowed. Using the results of the modeling, we discuss
implications for detection prospects by multi-messenger campaigns.
