A sector with QCD-like strong dynamics is common in models of non-standard physics. Such a model could be accessible in LHC searches if both confinement and big-quarks charged under the confining group are at the TeV scale. Big-quark masses at this scale can be explained if the new fermions are chiral under a new U(1)′ gauge symmetry such that their bare masses are related to the U(1)′-breaking and new confinement scales. I will present a study of a minimal GUT-motivated and gauge anomaly-free model with implications for the LHC Run 2 searches. We find that the first signatures of such models could appear as two gauge boson resonances. The chiral nature of the model could be confirmed by observation of a Z′γ resonance, where the Z′ naturally has a large leptonic branching ratio because of its kinetic mixing with the hypercharge gauge boson.
