We have constructed two chiral preon models based on the group SU(N)/sub MC/ x SU(N+4)/sub F/ x U(1)/sub F/ (MC is gauged metacolor and F is global color flavor), the simplest (M = 0) version of a class of models SU(N)/sub MC/ x SU(N+M+4)/sub F/ x SU(M)/sub F/ x U(1)/sub F/ /sup 2/ studied by bars and Yankielowicz. In contrast with earlier work, our models satisfy the principle of complementarity between the Higgs and confining phases. In one model, N = 16 and four generations of ordinary quarks and leptons are found at the gauged SO(10) level. The second model predicts three quark-lepton families at the gauged SU(5) level without a right-handed neutrino. We also show that complementarity holds for the Mnot =0 models but that, for N = 15 or 16, the results at the gauged level are identical with the M = 0 case.
