TacStar SideSaddle 12 Gauge 4-Rd Shotshell Carrier - Mossberg 500/590

The TacStar SideSaddle is a purpose-built 12 Gauge shotshell carrier that bolts directly to the side of your shotgun's receiver and keeps four extra rounds ready for fast, intuitive reloads. Designed specifically for the Mossberg 500 and Mossberg 590 families, this side saddle places spare shells within easy reach so you can stay on target without breaking your grip or shooting stance.

The shell-holding body is molded from tough black polymer with a smooth finish, and it attaches via an aluminum mounting plate that uses the shotgun's existing side mounting points. All mounting hardware is included, and installation requires no gunsmithing - the unit drops into place and is secured with the included mounting screws.

With a 4-round shell count, the SideSaddle adds meaningful extra capacity without snagging on gear, slings, or cover. It is a practical upgrade for home-defense, tactical, and range setups built around the Mossberg 500 or 590 shotgun.
