  In this work, we propose a search for a single photon at \texttt{FASER} and
\texttt{FASER2}, produced from decays of bino-like, sub-GeV lightest
neutralinos in the theoretical framework of the R-parity-violating (RPV)
Minimal Supersymmetric Standard Model (MSSM). We consider a list of
representative benchmark scenarios with one or two non-vanishing RPV couplings.
The photon has an energy
$\mathcal{O}\left(0.1\right)-\mathcal{O}\left(1\right)$ TeV. We find a
sensitivity reach for RPV couplings beyond the current bounds by orders of
magnitude at \texttt{FASER} and \texttt{FASER2}.
