The K/sub L/-K/sub S/ mass difference provides a stringent constraint on the mass (M/sub R/) of the charged right-handed gauge field occurring in a ''manifest'' left-right-symmetric electroweak theory, yielding M/sub R/> or approx. =1.6 TeV. Taken in the context of a grand-unifying gauge theory, e.g., O(10), such a large bound on M/sub R/, along with the measured value of sin/sup 2/theta/sub W/, implies that M/sub R/> or approx. =10/sup 9/ GeV.
