  In this note we report on the recent progress in the study of the strongly
interacting sector of the Minimal R-symmetric Supersymmetric Standard Model
(MRSSM). First, we discuss the limits originating from the search of the sgluon
pair production in the same-sign lepton final state at the LHC. Next, we
present the first available in literature calculation of the NLO SQCD
corrections to the same-sign squark pair production in the MRSSM. We discuss
the relative size of $k$-factors compared to the MSSM and some technical
details that led to this result.
