The detection of neutron-antineutron oscillation will be a discovery of fundamental importance in particle physics and cosmology. Models predicting them, usually, assume weak couplings at the scale of the experiment, although Nature has been quite evasive regarding the issue. Acknowledging this, we discuss a new non-perturbative mechanism, generated by confining New Physics in a linear moose, resulting in low-energy baryon number violating effects within the reach of current terrestrial and Neutron Star measurements.
