Abstract We introduce an in-depth study of an unprobed pMSSM region offering a natural solution to dark matter. Since the 1980s this region has been referred to as the "bulk", consisting of sub 200 GeV neutralinos and right-handed smuons. The bulk satisfies recent muon $g_{\mu}-2$ measurements and sustains consistency with $all$ presently operating SUSY experiments and LHC constraints. Initial ingress into the bulk will arrive soon via the LUX-ZEPLIN 1000-day experiment. Observation of these light right-handed smuon events could optimistically occur at the ongoing LHC Run 3 or forthcoming High-Luminosity LHC. If these light smuon events are ultimately deemed inaccessible at the LHC, then the future FCC-ee and CEPC circular colliders should handily observe the events.
