  Binary stars make up a significant portion of all stellar systems.
Consequently, an understanding of the bulk properties of binary stars is
necessary for a full picture of star formation. Binary surveys indicate that
both multiplicity fraction and typical orbital separation increase as functions
of primary mass. Correlations with higher order architectural parameters such
as mass ratio are less well constrained. We seek to identify and characterize
double-lined spectroscopic binaries (SB2s) among the 1350 M dwarf ancillary
science targets with APOGEE spectra in the SDSS-III Data Release 13. We measure
the degree of asymmetry in the APOGEE pipeline cross-correlation functions
(CCFs), and use those metrics to identify a sample of 44 high-likelihood
candidate SB2s. At least 11 of these SB2s are known, having been previously
identified by Deshapnde et al, and/or El Badry et al. We are able to extract
radial velocities (RVs) for the components of 36 of these systems from their
CCFs. With these RVs, we measure mass ratios for 29 SB2s and 5 SB3s. We use
Bayesian techniques to fit maximum likelihood (but still preliminary) orbits
for 4 SB2s with 8 or more distinct APOGEE observations. The observed (but
incomplete) mass ratio distribution of this sample rises quickly towards unity.
Two-sided Kolmogorov-Smirnov tests and probabilities of 18.3% and 18.7%,
demonstrating that the mass ratio distribution of our sample is consistent with
those measured by Pourbaix et al. and Fernandez et al., respectively.
