We propose a gravitational dual for ``single-sector'' models. These are supersymmetric extensions to the Standard Model where some particles of the Minimal Supersymmetric Standard Model MSSM)
are composites of a strongly-coupled gauge theory. The composite states feel supersymmetry-breaking directly. As a consequence, the spectrum of the MSSM is split: first and second generation squarks and sleptons obtain masses of order 5-10 TeV. The remaining MSSM fields experience gauge mediation. In our work, the single-sector scenario is expressed in a dual gravitational
AdS(5)-like description, inspired by flux-background solutions of Type IIB supergravity. These backgrounds have all supersymmetry broken in the depths of the ``throat,'' equivalent to the vicinity of the infrared brane. Specifically, the metric deviates from AdS(5) near the IR brane. A single parameter
characterizes the supersymmetry-breaking of the background in this MSSM-in-the-bulk model. Thus, the model is highly predictive. The collider signals are investigated and are shown
to be similar to gauge mediation with a neutralino NLSP that decays promptly to a gravitino LSP, but with rates that are lower by a factor of a few; the single-sector models can be detected and distinguished from mSUGRA and conventional gauge mediation with 1-10 1/fb of LHC data.
