Receiver-mount rails are made to be mounted onto the receivers of Mossberg shotguns pre-drilled and tapped for sights. These rails can also be used with weapons that are custom drilled and tapped. All Mesa Tactical Picatinny rails are machined from 6061-T6 aircraft quality aluminum, and finished with mil-spec Type III hard anodizing. Mesa Tactical Picatinny rails include all necessary mounting hardware.
