TacStar's SideSaddle mounts extra rounds on your shotgun in a convenient and accessible location for fast reloading. The 6-round polymer shell carrier is attached to an aluminum mounting plate that installs directly on the shotgun receiver. All mounting screws are included, and no gunsmithing is required. Note: some field-grade shotguns may require a modification to the shotgun's forend. Shotguns using the TacStar pistol grip forend do not require modification.
