It might require some modification or fitment, but it should fit the Pardner Pump as well.
No. The AIM Sports Tactical Shotgun Quad Rail w/ 6-Round Shell Carrier is designed to fit Remington 870 or 1100 shotguns only. I would recommend the Aimtech Warhammer Tactical Full Rail Shotgun Mount, found by using the link below:

No, this is only for Remington 870 and 1100 shotguns.
This should be compatible.
This is drilled specifically for the included shell holder, but it might be possible with some modification.
It may fit, but it has not been test fit by ourselves or the manufacturer. Because the DM model of the 870 uses the receiver pins for the magazine well, you may need to modify the rail to fit because it also uses receiver pins to mount to the receiver. So we unfortunately cannot guarantee it is going to fit properly as the rail and that specific model of 870 has not been tested.
No, this is meant specifically for the Remington 870. You could use this instead, but its not a quad rail and is instead a keymod rail so it will accept keymod rail sections and accessories:

The top rail per AIM Sports is a M1913 picatinny rail.
This is meant for a Remington 870 specifically and cannot be guaranteed to fit any other model of shotgun.
