Mossberg 500 Shot Shell Carrier

Six-Round Side Saddle

The AIM Sports MM6RK is a side saddle shell carrier for the Mossberg 500. It mounts on the side of the receiver, the metal housing that holds the action, so six spare 12-gauge shells ride on the gun itself instead of in a pocket or pouch. It suits home-defense, duty and range shooters who want reloads within reach of the support hand.

Features

• Six-Shell Capacity — Six individual cups hold 12-gauge shells in a single row along the receiver.
• Side Saddle Configuration — The carrier sits flat against the side of the gun, so it adds ammunition without adding a separate piece of kit to carry.
• Quick-Detach Carrier — The shell holder slides off its mounting plate without tools, so you can swap in a loaded carrier or strip the gun down for storage.
• Polymer Shell Holder — The black polymer cups are split along their length so they flex to grip each shell and release it with a firm pull.
• Aluminum Mounting Plate — The base plate that attaches to the receiver is aluminum and stays in place when the carrier comes off.
• Mossberg Compatibility — Built to fit the Mossberg 500, 500A and 590 shotguns.
• Compact Footprint — The unit measures 7 in (178 mm) long by 2.4 in (61 mm) wide and weighs 5.03 oz.
• Hardware Included — All mounting hardware needed for installation comes in the package.

Build And Fit

The carrier pairs a black polymer shell holder with an aluminum plate, and the two lock together along rails on the plate's long edges. A threaded hole in the plate's angled front tab is part of the mounting system, and the included hardware covers installation. At 5.03 oz empty, it adds little weight to a Mossberg 500, 500A or 590.
