ATI Outdoors Advanced Technology 12GA Side Saddle Shell Holder – Mossberg/Remington/Winchester

The ATI Outdoors Advanced Technology 12GA Side Saddle mounts directly to your shotgun receiver, providing immediate access to six additional 12-gauge shells. This shell carrier eliminates fumbling for loose rounds during reloads—whether you're running tactical drills, hunting in dense cover, or keeping a home defense shotgun ready. The side saddle positions shells horizontally along the receiver, allowing ambidextrous access without interfering with optics or charging handles.

Constructed from impact-resistant polymer with an integrated aluminum mounting plate, this shell holder installs using existing receiver pins on compatible Mossberg 500/590, Remington 870, and Winchester 1200/1300 models. Installation is straightforward with basic tools but requires partial disassembly of the trigger group. The polymer loops grip shells securely while still allowing quick single-hand extraction. Elastic retention keeps rounds in place under recoil and rough handling without requiring constant adjustment.
