TacStar Slimline Sidesaddle – Mossberg 500/590

The TacStar Slimline Sidesaddle adds six rounds of on-gun ammunition storage to your Mossberg 500 or 590 shotgun without adding unnecessary bulk. This receiver-mounted shell carrier keeps additional rounds within immediate reach for tactical applications, home defense, or competition use where fast reloads matter.

The low-profile design positions shells close to the receiver to minimize snag hazards and maintain the shotgun's handling characteristics. Constructed from impact-resistant polymer with a matte black finish, the sidesaddle installs without permanent modification to the firearm—it mounts to existing receiver pins. Shells are held securely under tension but release quickly when needed.
