This system is only one of 3 field age ($>$ 1 Gyr), late M dwarf eclipsing binaries known, and has a period of 1.74774 days, similar to that of CM~Dra and KOI126. Modelling of the eclipses and radial velocities shows that the component masses are $M_{\\rm pri}$=0.17391$^{+0.00153}_{0.00099}$ $M_{\\odot}$, $M_{\\rm sec}$=0.17418$^{+0.00193}_{-0.00059}$ $M_{\\odot}$; radii are $R_{\\rm pri}$=0.2045$^{+0.0038}_{-0.0058}$ $R_{\\odot}$, $R_{\\rm sec}$=0.2168$^{+0.0047}_{-0.0048}$ $R_{\\odot}$.
