Aim Sports MR6RK Side Shell Carrier Rem 870 12 Gauge 6 Rounds Black Polymer

The Aim Sports MR6RK is a side shell carrier (sidesaddle) purpose-built for the Remington 870 pump-action shotgun. Designed as a quick-detach, drop-in upgrade, this carrier attaches to the receiver via an aluminum mounting plate and adds six ready-to-grab 12 Gauge shell positions alongside the receiver, dramatically speeding up tactical and competition reloads.

The carrier body is molded from durable black polymer with a smooth finish, while the included aluminum mounting plate screws directly to the receiver for a secure, no-slip fit. The shell holder then slides into two grooved rails on the plate, allowing the shooter to remove or reattach the sidesaddle in seconds without tools. Six individually separated compartments hold standard 12 Gauge shells secured and ready for an immediate reload.

This is a drop-in upgrade that preserves the factory lines of the Rem 870 and keeps spare shells staged right at the receiver for fast access. All mounting hardware is included for installation out of the box, making it a straightforward add-on for home defense, tactical, or 3-Gun style setups where keeping six spare shells at the receiver is a clear advantage.
