  We study the low-scale predictions of the supersymmetric model extended by
$U(1)_R \times U(1)_{B-L}$ symmetry, obtained by breaking $SO(10)$ symmetry at
GUT scale via a left-right supersymmetric model. Two new singlet Higgs fields
($\chi_R$, $\bar{\chi}_R$) are responsible for the $U(1)_R \times U(1)_{B-L}$
symmetry breaking to the standard model gauge group. We explore the
phenomenology of this model by assuming universal and non-universal boundary
conditions at the GUT scale and their effects in obtaining consistency among
low-energy observables, dark matter experiments, muon magnetic moment
measurements, and $Z^{\prime}$ phenomenology. We examine different scenarios
with both the lightest neutralino and sneutrino mass eigenstates as the dark
matter candidates that satisfy all the experimental constraints. We explore the
collider signals of various scenarios including different benchmarks and their
significance versus standard model background. To complement our analysis, we
perform recasting of several LHC analyses to verify the credibility of
different benchmarks. We find that relaxing the universality conditions at
$M_{\rm GUT}$ can significantly improve the agreement of the model against the
experimental bounds. While the muon anomalous magnetic moment is found to be
the most challenging observable to fit with the model, we find points in the
parameter space consistent within $2 \sigma$ from the average measured value,
employing non-universality at the GUT scale.
