We prove that every right-angled Artin group occurs as a finite-indexsubgroup of the outer automorphism group of another right-angled Artin group.We furthermore show that the latter group can be chosen in such a way that thequotient is isomorphic to $(\mathbb{Z}/2\mathbb{Z})^N$ for some $N$. For these,we give explicit constructions using the group of pure symmetric outerautomorphisms. Moreover, we need two conditions by Day-Wade and Wade-Br\"uckabout when this group is a right-angled Artin group and when it has finiteindex.
