  We study the recently proposed AdS$_7$/CFT$_6$ dualities for a class of 6d
$\mathcal{N} = (1,0)$ theories that flow on the tensor branch to long linear
quiver gauge theories. We find a precise agreement in the symmetries and in the
spectrum of charged states between the 6d SCFTs and their conjectured AdS$_7$
duals. We also confirm a recent conjecture that a discrete $S_N$ symmetry
relating the baryons in the quiver theories is in fact gauged.
