Mossberg 590S models set a new standard for shotshell cycling flexibilty. Now, we've added the added benefit of optic-ready convenience. Receiver cuts allow 590S shotguns to accept low-profile direct mounting of Shield RMSc-pattern micro dot sights, for improved eye alignment and target acquisition. Cover plate is included when a sight is not mounted.
