  We investigate the emergence of both quantum anomalous Hall and
disorder-induced Anderson Chern insulating phases in two dimensional hexagonal
lattices, with antiferromagnetically ordered 3Q state and in the absence of
spin-orbit coupling. Using tight-binding modeling, we show that such systems
display not only a spin-polarized edge-localized current, the chirality of
which is energy dependent but also an impurity-induced transition from trivial
metallic to topological insulating regimes, through one edge mode plateau. We
compute the gaps' phase diagrams, and demonstrate the robustness of the edge
channel against deformation and disorder. Our study hints at the 3Q state as a
promising building block for dissipationless spintronics based on
antiferromagnets.
